I know there's probably a lot of sensitivity about going into the "polls are skewed" thing, especially when approaching a respected pollster like Pew. So I won't unskew at all...I'll just present some demographic info from page 14 of the PDF of the today's poll showing Romney ahead by 4, and you can make your own judgments or calculations as you see fit in the comments:

Reps: 392

Dems: 361

50+ voters outnumber everyone else more than 2-1

White (non-Hispanic) voters surveyed: 869

Everyone else: 173 (!!!)

Note: This is from the LIKELY VOTER column.
