I'll give it a go:

Obama by ten to fifteen points in the popular vote, winning 430 electoral votes, including Georgia, Texas and Montana as well as all the "battleground" states. This is predicated on a 70+ percent turnout. Much lower than that and we are in for a rough night.

I say a 60 seat majority in the Senate, though that will be close. Haven't been following the House races as I live in DC and have a hard enough time getting excited for senate races.

I will add this, though, if a better republican running for the senate in Virginia, Mark Warner would be having a hard time because as far as I can see, his campaign has been lackluster at best.

Of course, I have been predicting the American voter to wake up for years and have been disappointed before, most recently in 2006 when only 43% turned out to vote. Don't even get me started on the ten-percent average turnout for primary elections when the name says all we need to know about their relative importance to the process. We should calling the General Election the Secondary Election in order to change the context a bit.

We have a voter ignorance and apathy problem in this country that will take multiple elections and a concerted education effort to fix for good.

Nader by a landslide

We have the socialist Obama right where we want him.

We will take back all of the electoral votes. We will take back all the senatorial seats. We will create the permanent Republican majority envisioned by the Prophet Gingrich.

We will leave your women weeping inconsolably.

Everything you know is wrong.

Obama in popular vote by 3%
Electoral College - 380
He wins in Fl, NC, NM and possibly montana.
Blame pasted squarely on Ms. Palin for the loss by the msm et. al.

EV
Obama 353
The Deformities 185

Popular Vote
Obama 52
McPiglin 45
Other 3

Senate Dems pick up: CO,NM,VA,NH,NC,AK = 56-44 (Mentum dumped please G-D)

House - Dems pick up 27 seats

Obama wins 51% of the popular vote.

Somewhere between 338 to 353 EVs, with a high probability of 344. If you're scoring at home, my 344 map looks like this:

All the Kerry states plus Virginia, Florida, NC, CO, NM, NV, Iowa, and one of Missouri or Indiana.

I think there's an outside chance of getting to 375 if Obama wins Ohio, Indiana, and Missouri.

344 may be a little optimistic with NC in there, but I think it's doable, especially given the early voting numbers out of the state.

As for the Senate, I just want Al Franken to win. That would make my life.

Electoral Votes:
McCain: 195, Obama 348
Senate Republicans 41, Democrats 58 plus Sanders and Lieberman
House of Representatives Rep: 172, Dems 263

Dems pick up 28 seats in the House

Percentage in presidential campaign:
McCain: 45.4% Obama 53.6%

First, I think we have to distinguish an HONEST election from election fraud. In a (reasonably -- as there is always SOME cheating) HONEST election, I think that Obama could be projected at about ~53% of the vote, possibly much higher as progressives feel INspirited and the RW DISpirited, in most of the country. That would mean a win of 7% or more.

In that scenario, the electoral college would be a blowout, with Obama receiving surely over 300 and quite possibly as high as ~350. I think it overoptimistic that so many on this thread PREDICT OVER 350 electoral votes, often many more, as that would imply Obama winning almost every single state that is seriously in play. Dick Morris argues with some merit that undecideds would likely break for McCain, but other factors than the logic he puts forward (election is a referendum on Obama) could at least make MOST undecideds, but hardly an overwhelming majority, break for Obama. Predictions of a 15% victory and over 400 electoral votes are off the radar screen.

On the other hand, there is the question of how successful the GOP will be at stealing the election. Note that they would have to steal multiple states, and not just one big one as in 00 and 04. This I don't think is likely, but it is possible, depending on to what degree they can exact obedience. It's pretty clear that, once stolen, the process will not AT ANY LEVEL hold the thieves or thieving party seriously accountable. Even with the degree of cheating that I expect will happen, I think Obama will STILL garner a majority of the votes and a strong majority of the electoral college -- winning the election by more than one even large "contested" state.

In the senate, the possibility of the Democrats getting 60 (in which case it would be up to the most RW of the Democrats caucusing, like Lieberman, to sustain filibusters) looms larger and larger. The smart money is predicting that the Dems come out with 58 or 59, but I see as high as 61 as a possibility, albeit an outside one.

In the House, the large majority already enjoyed by the Democratic Party will expand significantly, by at least another 27 seats, possibly many more. But the limits of what a likely Democratic Administration can do will be set by the possibilities of a filibuster in the senate, and a likely VERY activist RW SCOTUS for years to come

In the spirit of those TV poker shows, I'm going for the high-low here.

High:
Obama 55% - 41% (4% to 3rd-party candidates)
Democrats 60 Senators

Low:
Obama 51% - 47% (2% to 3rd parties)
Democrats 57 Senators

If I'm right with either scenario, I'll split the pot with my closest competitor. ;)

Ptroub, are you sure Kerry was leading in 2004? I remember him being behind. People thought he would win because the undecideds were supposed to break for the challenger, not because he was actually leading.
