'These polls are skewed -pay them no mind...' Is this seriously going to be our argument?
I think you're missing the point. The GOP is doing well, no question and will probably pick up the Senate... but unlike 'unskewed' from 2012, which was based on a complete misunderstanding and fantasty mind-set, there is consistent evidence that Democrats do have a tendency to be undervalued in polls, especially in certain states. That's not some grand conspiracy theory, it is backed up with evidence.
I think in a few states, CO in particular, but possibly GA too, among others the polling is showing you the trend and the tilt, but the Democratic position may be being under-valued. I don't know about anybody else, but that's my view. It might not mean much in the end, but it might just mean the races end up much closer than what might be being presumed from polling.
