The state of Ohio is perhaps the most critical swing state this election, and the latest polls are strong evidence that President Obama's got it locked up.

Via Nate Silver on Twitter:

7 polls released in Ohio in past 48 hours: Obama +2, Obama +3, Obama +3, Obama +3, Obama +5, Obama +5, Obama +5. #notthatcomplicated

Another sign things are looking good?  Republican pundits are complaining about biased polling again.

Harry Enten addresses this:

I learned a powerful lesson eight years ago: polling averages work. The averages have correctly predicted all state presidential contests except for five since 2000. They have accurately projected every Senate winner, save a few, over the last few years. The state polling averages say Obama is going to win.

There is a crowd, however, that believes the polls have too many Democrats. They look at the polling data and see the same, or even higher, percentage of poll respondents in states like Ohio self-identifying as Democrats than the polls had in 2008 – a year of record high enthusiasm for Democrats.

My personal opinion is that the polling averages are likely correct. I witnessed Democrats making the "skewed" argument in 2004 when polls showed "too many Republicans". The averages won, and George W Bush served another term. We'll see, though, if I'll be eating my words.
