I just can't imagine how some can project a November winner from the Democratic Primary winners, state by state. It makes no sense to me. For example, "Hillary has won NY and CA - we need those states to win, therefore she should be our nominee." Most people here, I think, see this for the absurdity that it is - however for the benefit of the rest, let's do a little electoral analysis.
(Before I do that, let me just say that I completely agree with the 50-state strategy; we should not assume blue states will stay that way for purposes of the general election campaign, nor allow red states to be uncontested.)
The following states have been consistently blue in each election from 1992 to 2004:
California, Connecticut, Delaware, District of Columbia, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington, Wisconsin
Total electoral votes, 248
The following states have been consistently red in each election from 1992 to 2004:
Alabama, Alaska, Idaho, Indiana, Kansas, Mississippi, Nebraska, North Carolina, North Dakota, Oklahoma, South Carolina, South Dakota, Texas, Utah, Virginia, Wyoming
Total electoral votes, 135
IT ONLY TAKES 270 TO WIN, PEOPLE! WE ONLY NEED 22 MORE.
This shouldn't be hard, but somehow it has been for Democrats the last two elections.
Okay, now we have three states that lean blue (3 out of the last 4 elections): Iowa, New Hampshire, and New Mexico.
That's 16 of the necessary 22 swing electoral votes we need if we can carry them this year, assuming the Blue states stay Blue.
The above three states have pretty much been a statistical toss-up between Clinton and Obama. 38 delegates for Clinton, 37 for Obama.
We have five states that lean red (3 out of the last 4 elections): Arizona, Colorado, Florida, Georgia, Montana
I REPEAT: Florida is a red-leaning state. Furthermore Edwards was on the ballot and gained 14.4% of the vote there. The vast majority of his support has since moved to Obama. Those claiming that Hillary has a better chance of swinging this state in 2008 had better come up with a new argument because there's just no way to know for certain just going by those election results, and in any case there's still a good chance that the state will remain red.
Get the stars out of your eyes with regard to Florida's 27 EV's. We don't need that many. If you really think this is such a big deal, Obama won Georgia 66% to 31% - there's 15 EV by your same logic. Yes, that was a primary not a caucus. That would only leave 7 more EV's necessary to win the election - or, it would WIN the election for us if Obama also won Iowa. 15+7=22, there's some simple math.
Of the remaining red-leaners, Clinton's slight advantage in Arizona (10 EV) is balanced out with Obama's convincing win in Colorado (9 EV). Montana has yet to vote.
So that brings us to the true swing states. They all went Blue in 1992 and 1996, and Red in 2000 and 2004
Arkansas, Ohio, Tennessee, Louisiana, Missouri, Nevada, Kentucky, West Virginia
Obama convincingly won Louisiana (9 EV) which cancels out Clinton's convincing Arkansas win (6 EV). Kentucky and West Virginia have yet to vote. Missouri and Nevada were statistical ties.
If you look at this graph from Pollster.com you can see that Obama could easily have won Ohio given a few more weeks of campaigning.
That leaves just Tennessee with its 11 EV's as an advantage for Clinton among swing states, and there are plenty of combinations without TN that would swing the election our way (not that I'm conceding TN if Obama wins the nomination).
Now is that enough of a convincing advantage to make you choose Clinton over Obama, just on the basis of "electability"?
I'd say, probably only if you've already decided she's your candidate.
