In Maine, we have Susan Collins(R) fading, she is now leading Tom Allen(D) by 49%-42%, but any incumbent below 50% is in trouble, and not so long ago it was something like 52-39.

The one that surprises me though are the numbers for Mississippi, where the kinda-sorta incumbent^* Roger Wicker(R) is behind Ronnie Musgrove(D) 46%-47%.

I would not expect that in Mississippi.

^*Wicker has been in the Senate for only a few months, he was appointed to replace Lott when he retired to become a lobbyist .
