In North Carolina, it still looks like Sen. Richard Burr (R) can be defeated, but it would be easier if he were running against a "generic" Democrat:
45% Burr, 38% Generic Democrat
41% Burr, 34% Bob Etheridge
42% Burr, 31% Elaine Marshall
42% Burr, 31% Dennis Wicker
42% Burr, 30% Cal Cunningham
43% Burr, 29% Kevin Foy
43% Burr, 27% Kenneth Lewis
It really might not matter who the Democratic candidate ends up being. With Burr's numbers where they are, if the political climate moves back in a Democratic direction any candidate who can raise some money, has something to say and can avoid making a fool of themselves is probably going to beat him. But if things stay the way they are today, or move in a more Republican direction, none of them are going to beat him. -PPP
Elizabeth Dole led Kay Hagan 43-27 in their first matchup two years ago, so in reality there's plenty of time for a Democrat to win.
And in CT:
Rob Simmons (R) 49%, Chris Dodd 39% (Rasmussen)
That's basically the same as Quinnipiac had it in July, Simmons 48%, Dodd 39%, so nothing much has changed in two months.
