Your statement was that Michigan, Wisconsin, and Pennsylvania were competitive. They aren't. Michigan and Pennsylvania in particular are very very small probability states for a Romney win. If you believe they're competitive you're either in an echo chamber or you're cherry picking poll numbers.
The numbers over the last week + have been quite poor for Romney in battleground states. Thursday's polls of battleground states had 9 polling for Obama vs. three for Romney. Friday's round of polling featured 11 polls favoring Obama vs. four for Romney. Michigan and Pennsylvania aren't even being tracked in swing state polls by most sources.
The Virginia polling average from Nate Silver and Emory's own Drew Linzer (which use significantly more and better data than RCP) indicate an unadjusted average of 47.6% for Obama and 46.8% for Romney. After adjustments for house effects, sample sizes, field dates and the like the numbers favor Obama by just .1%. If that's not a "virtual tie" I don't know what is.
Romney is probably going to get Florida. No argument.
I said it was over based upon the available polling data and virtually all solid statistical analysis of the race. That's not just a feeling. There hasn't been any point in this race where that information indicated Romney was actually ahead in electoral count. The direction was a littly scary following the first debate, but we're past those days as the electoral numbers have been slowly going back to where they were before the debate. Obama's probably regained about half the ground he lost. At this point it looks more like Obama's getting to 300 electoral votes than falling below 270.
You said you can see Romney taking Wisconsin. I think that's pretty close to a 1 in 10 chance at best. I'm saying that looking at poll numbers and looking at sophisticated simulations of the race that give not just average results but voting bands of probable results. The Wisconsin bands are very narrow.
Romney's campaign keeps saying things about Penn, but not committing any resources there. I don't believe they have any intention of contesting the state.
