More fodder from around the country:
Taegan Goddard at Political Wire
recaps the following bites:New Hampshire: Former Governor Jeanne Shaheen "has not ruled out" a rematch run against Republican freshman Senator John Sununu. Given New Hampshire's strong blue streak in 2006, giving Democratic Governor John Lynch a record re-election and turning both Congressional seats from R to D, this would be very good news for Democrats and very bad news for incumbent Sununu.
Minnesota: Comedian/commentator Al Franken said that he would decide over the coming weekend whether or not to challenge incumbent Republican Norm Coleman.
Texas, Oregon, and Maine: kos at Daily Kos recaps a Hotline piece outlining potential Dem challengers to incumbents in those three states. The most promising pickup of the three is Oregon, with ex-Governor John Kitzhaber as the Democratic "lion in waiting."
UPDATE (12:28 PM): Jonathan Singer at MyDD takes a look at New Hampshire and the same Hotline piece that kos does.
