This Week’s Notes
This week we got to see the full effect of McCain’s convention bounce as I added polls for 33 states this week (2 were from older polls that I missed). Every single Weak or Too Close To Call state has had at least one post-convention poll except for Indiana (!?) and South Dakota now, and given they both sit on McCain’s side of the fence, it’s not that big of a deal.
So what are the full effects of the McCain convention bounce over the past two weeks? Obama’s Electoral College lead had gone from 70 down to 11 – Obama’s smallest lead he’s ever had (he was behind in the very first week on June 10th).
Obama has dropped from 243 Weak or Strong Electoral Votes down to 197, losing Minnesota, New Mexico, Pennsylvania, and Wisconsin to the Too Close To Call category (though they all remain lean Obama states).
Meanwhile, McCain has risen from 173 to 186 Electoral Votes, gaining Alaska, Montana, North Dakota, and North Carolina, but losing Indiana to the Too Close To Call category (note: the poll dropping Indiana is post-Democratic Convention, but pre-Republican Convention).
Meanwhile, Obama’s lead in the Electoral Count with leaners, which was already steadily declining, dropped from 30 to 8, just above the smallest lead he ever had (6 EVs, on both June 10th and 17th) and now sits at 273-265 in favor of Obama.
This week we had 10 states change status, 9 in favor of McCain.
Delaware is the lone state which moved in Obama’s direction. It had been sitting as a Weak Obama state forever due to the fact that it only had a single poll from back in February. Now that someone decided to actually poll the place, it has moved up to Strong Obama.
One state whose move down I find rather dubious is New York’s. Very, very few polls have shown that state to be close. However, since my polls age over time, and the last poll taken in the state had been done nearly a month before, the new poll showing McCain within 5% carries a lot of weight. While New York is officially Weak Obama, until we get another poll which confirms this last one (and I’ll be shocked if one does confirm it), I’m still treating it as effectively Strong Obama.
The eight other polls are either McCain shoring up Bush states (Georgia, Montana, North Carolina, North Dakota) or Obama states dropping (Minnesota, New Jersey, New Mexico, Wisconsin).
All in all, one cannot deny that the past two weeks have been very good for John McCain. Except for one item: He’s still behind. We’ve now had polls in a variety of states that cover the entire week following the Republican Convention and then some – a time period which one would expect McCain to peak – and yet he still can’t get enough states to defeat Obama, at least as of now.
That’s not to say Obama isn’t in a pecarious position. The state which would swing the election, as it has been pretty much for weeks, is Colorado, where Obama holds on with a 0.9% lead. On the other hand, McCain only currently holds Virginia by a 0.3% lead, so McCain can’t necessarily say that he is definitely going to get all the states he currently has on his side either. McCain is also only ahead in Nevada by 1.2%, while the margin in Michigan, Ohio, and Pennsylvania are all 2.3% (with New Mexico following at 2.5% and Wisconsin at 2.8%. Everyone else is effectively 4% ahead or more).
We’re likely not going to see much changes in the Electoral College before the 1st debate, since state polls tend to lack the national polls, if for no other reason than because they’re not taken as often, though that may start to change now that we’re only 49 days from the election.
All of this pretty much boils down the election to 8 battleground states: Colorado, Michigan, Nevada, New Mexico, Ohio, Pennsylvania, Wisconsin, and Virginia, with 3 super-battlegrounds: Colorado, Nevada, and Virginia. If Obama wins any of those three states, he comes away with at least a tie.
So, what happens if we get a tie? Given the current make up of the US House, Democrats hold 27 delegations, which would give Obama the Presidency. But what if things go sour and we lose two delegations and we drop to 25? This is where we get into nice nightmare scenarios.
First, the 12th Amendments mandate that a candidate get an absolute majority of states, meaning 26. If the US house votes 25 for Obama, 22 for McCain, with 3 abstentions due to ties, that won’t cut it. Someone needs 26 states. That means there maybe some very lucky Republicans or Democrats who may be swayed into voting into the other candidate in return for, say, a high level cabinet position or something.
But what if no one budges and we can’t get a majority in the House? Then the Vice President acts as acting President. The Vice President is chosen by a majority vote in the US Senate. There is one problem: based on the current make up of the Senate, we’re looking at a 50-50 tie there, assuming Lieberman votes for Palin and not Biden. What happens then?
The 12th Amendment says one needs an absolute majority of Senators, but it doesn’t say what happens if the Senate can’t decide on a Vice President, either by a 50-50 tie or abstentions which leaves no candidate with 51 votes. It is quite possible that in this nightmare of nightmare scenarios, Dick Cheney could cast a tie-breaking vote for the next Vice President, and thus acting President: Sarah Palin. If the Senate rules that the Vice President cannot cast a tie-breaking vote in a vote to elect the Vice President, then the 20th Amendment suggests that me move on in the order of succession, which means that the Speaker of the House, presumably Nancy Pelosi, would become acting President, until and unless either the House or the Senate breaks it’s deadlock.
Oh, and one more note: I’ve been creating a pollster.com-ish type website to do this. I haven’t decided whether I’ll still post a Tuesday morning update on here or not, but that site will be constantly updated with the most recent polls so you’ll always know what the current status of the Electoral College is. I hope to have it fully up and running by the weekend.
Historical Graph
Click for bigger version:

Obama has been in kind of a freefall in the two weeks since the Republican Convention. He obviously needs to stop and revere that if he wants to win in November. McCain is getting closer to, but still can’t break the 200 EV mark.
Polling Wish List
Finally, my polling wish list for this week is:
- Arizona – Weak McCain, no poll for 31 days
- Indiana – Too Close To Call, no poll for 16 days
- South Dakota (7th week) – Too Close to Call, no poll for 68 days
- Texas – Weak McCain, no poll for 25 days
- Wisconsin – Too Close To Call, no poll for 9 days
On Deck: I think I can finally get rid of the on deck circle
States which haven’t had a new poll in over a month:
Arkansas, Arizona, Connecticut, DC, Hawaii, Illinois, Kentucky, Massachusetts, Nebraska, South Carolina, South Dakota, Vermont
Sister states
These are states for each candidate where the margin in those states are within 1% of each other and are within 3 total electoral votes or 33% of electoral votes of the smaller state of each other.
- Michigan (Obama, 17 EVs, +2.3%) and Ohio (McCain, 20 EVs, +2.3%)
- Pennsylvania (Obama, 21 EVs, +2.3%) and Ohio (McCain, 20 EVs, +2.3%)
- Minnesota (Obama, 10 EVs, +3.9%) and Indiana (McCain, 11 EVs, +4%)
- New Hampshire (Obama, 4 EVs, +4.5%) and South Dakota (McCain, 3 EVs, +4.2%)
- Washington (Obama, 11 EVs, +5.8%) and Missouri (McCain, 11 EVs, +5.2%)
