Lots of Reptile denial in this thread. The Midwest firewall makes a Roms victory impossible. Zero chance. Obama leads in the polls and his ground game is unprecedented. That 2-3% lead in the Ohio polling aggregate will translate to 4%+ on election day.
I've heard cons basically advance 3 arguments:
1. "The polls are assuming 2008 turnout!"
WRONG. These right wing blogs are mistaken. The only thing that measures "turn out" is the likely voter screen. They basically ask how sure you going to vote. THAT is how they factor in turn out.
This D v. R weighting argument is pure ignorance. Rasmussen does it this way, and they assume every poll does it. But it's not a good methodology. It is basically assuming what you are trying to determine. D/R/I is very fluid. Most independents are actually pretty extreme partisans (Think Teabaggers, who call themselves "independents" but in reality are as reliable for the GOP as they were in 2008). So the partisan ID is an output of a poll-- not an input.
These pollsters aren't assuming X many Democrats are going to turn out. People are telling the pollsters they are Democrats.
2. "Ohio is showing more Republicans voting than Democrats!"
TRUE, but misleading. As I've mentioned many times on here, Ohio identifies its voters by what primary they participated in. The Democrats had no contested primary at the president and senate levels, which means far fewer Democrats took a primary ballot. Plus, some Democrats voted in the GOP primary just to create mischief.
Ohio only identifies party ID if you've voted in a primary the past 2 years, which means everyone who took a Democratic ballot in 2008 but didn't vote in this primary or the 2010 midterms (in which Dem turnout was very depressed) was counted as an independent by the state of Ohio, greatly underrepresenting Democratic turnout in figures released thus far.
3. "Republicans are leading early voting nationally!"
TRUE. But, this is because of the heavily GOP South, which has more early voting opportunity than other regions. And national numbers don't matter, because here in America boys and girls, we elect our president state by state with an electoral college.
Also, Obama actually leads in the national polls as of yesterday. Though to be fair, Gallup has suspended polling the last few days.
But again, we live in America boys and girls, and America elects its presidents by an electoral college system, and in the battleground states, Obama has comfortable leads (or, at least comfortable for this close to the election).
National Prediction: Obama 50%, Romney 49%
Ohio: Obama 52%, Romney 47%
Electoral college: Obama 332, Romney 206
Senate: Democrats (+ Sanders and King) 52
House: Republicans +15
Roms fuct.
