Swing State Overview (270 to win, 269 to tie)
(Swing States are defined as states closer than 5.0%. If a state isn't listed, it isn't that close right now.)
State EV's Obama % McCain % Margin Obama Total
Obama Base 176 176
Minnesota 10 47.0% 46.0% +1.0% 186
Washington 11 47.0% 43.0% +4.0% 197
New Mexico 5 48.0% 44.7% +3.3% 202
Wisconsin 10 46.0% 43.0% +3.0% 212
Michigan 17 47.5% 44.8% +2.7% 229
Pennsylvania 21 46.5% 46.5% Even 250
New Hampshire 4 47.0% 47.0% Even 254
Colorado 9 46.4% 46.8% -0.4% 263
Virginia 13 47.2% 48.0% -0.8% 276
Indiana* 11 43.0% 45.0% -2.0% 287
Ohio 20 44.8% 47.9% -3.1% 307
Nevada 5 44.0% 48.5% -4.5% 312
West Virginia 5 44.0% 46.5% -4.5% 317
McCain Base 221 221

* = Reflects polling from before the Republican convention

Just as he falls behind in national polls, McCain has just moved into the lead in the electoral college. This odd development is due to the information lag between new national polls and new state polls. Much the same happened last week, as McCain moved clearly into the lead in national polls, but never lead by more than 270-268 in the electoral college (and sometimes didn't lead at all). McCain's lead in today's chart probably reflects where the campaign was five or six days ago, just as Obama's swing state lead last week represented the state of the campaign a few days before that.

Hopefully, at some point, there will be tracking polls in the closest states, thereby giving us up to date information on the actual state of the campaign. For now, what state by state information we have can be found in the extended entry.

* Maine's four electoral votes are awarded as follows: two for the statewide winner, and one for the winner of each congressional district. ME-01 is about 3.5% more Democratic than the state as a whole, while ME-02 is about 3.5% less Democratic than the state as a whole.

** Nebraska's five electoral votes are awarded as follows: two for the statewide winner, and one for the winner of each congressional district. NE-01 is about 6.0% more Democratic than the state as a whole, NE-02 is about 11.0% more Democratic than the state as a whole, and NE-03 is about 18.0% less Democratic than the state as a whole.

Methodology
The forecast is updated whenever there are enough new polls to warrant an update. The methodology for the forecast is simple and straightforward.

  1. For each state, all polls conducted entirely or partially within the last 15 days are included in the averages. There are two exceptions to this rule.
  2. The first exception are states where no polls were conducted entirely or partially in the last 15 days. Every state has at least one poll.
  3. The second exception comes with polling firms that have conducted more than one poll in a state over the last 15 days. Every polling firm only has one poll per average.
  4. No polling firm discrimination whatsoever. Polls are never excluded because the organization has a bad or partisan reputation.

During the final two weeks of the election, only polls taken entirely within the past seven days will be included in the averages (with the same exceptions listed above, of course).

Gallup: 0 47 - M 45 !!!!!!!!!!!!!!!!!!!!!

VA numbers (0.00 / 0)
How'd you come up with your VA numbers?

You say you have 5 polls. Did you throw out Zogby internet and include today's PPP poll?

For my 5 polls I get,
Fox/Rasmussen - 48M - 48O
SUSA - 46M - 50O
CNN - 50M - 46O
Rasmussen - 49M - 47O

and then today's PPP
M46 - O48

That gives me an average of 47.8M and 47.8O.

Does that square with what you have?


Right (4.00 / 1)
That's with the last 4 polls. I was going by Chris saying he used 5 polls. I think Chris made a mistake there somewhere. So it should either be tied in VA or Obama up 0.5% as you say.

Illinois is "lean blue" (4.00 / 2)
and Iowa is solid blue? Please. I don't care what numbers went into this -- it's so ridiculous as to make this whole exercise useless.

Is the math right here? (0.00 / 0)
I feel like you've shortchanged Obama 10 EVs somewhere. With the Kerry states +Iowa+NM+NH+CO aren't we over the top at 273? I'm looking at the chart and going crazy trying to figure out how we end up 10 behind with those states.

Yes, NH is a Kerry state n/t (0.00 / 0)

see my comment below. (0.00 / 0)
He misplaced MN's 10 electoral votes somehow (even though it says it's up there). Obama is at 264 (up to NH), not 254.

[ Parent ]
mistake on EV's (4.00 / 1)
Your Obama base numbers should be 143, not 133.
Your Obama lean numbers should be 86, not 96.

I think you forgot to count MN in your base numbers and somehow it screwed up your total EV count.

Obama should be at 264 once you count NH, not 254. This makes sense because Kerry had 252 EV. There's no way to get to 254 if you count all Kerry states plus NM and IA. But NM + IA = 254 - 12 = 242 which is 10 off from Kerry's total, so there's the missing MN EVs.
 


Ah, thank you (0.00 / 0)
Before seeing your comment, I had noticed that the numbers didn't add up but wasn't sure where they were wrong.

Plus after fixing VA (0.00 / 0)
Obama should be up to 277 EVs up through NH and VA. Much better than 254!

[ Parent ]
Also (0.00 / 0)
McCain 241, Obama 229, Toss-Up 168 = 638 EVs.  So I'm guessing that tossup number should be 68 instead?

where are you getting 168? (0.00 / 0)
It doesn't say that anywhere that I can see.

Top line of the entire post (0.00 / 0)
Above the map.

[ Parent ]
ah. gotcha (0.00 / 0)
it's correct down in the post, but I see now.

[ Parent ]
Nope (0.00 / 0)
There are 638 EVs in play this time. BOTH candidates can reach 270...everyone's a winner!
