Looking ahead to 2008, where are the most vulnerable Senate seats for both Republicans and Democrats?
For Republicans I see New Hampshire and Oregon as toughest to hold. Some point to Allard's Colorado seat as a weakness but Colorado is too conservative to vote for the liberal Mark Udall. That's a moderate hold for the GOP.
For Democrats I don't think they'll lose any more than the Louisiana seat and maybe, if Tim Johnson retires, South Dakota. Max Baucus is too popular in Montana to lose.
This is better suited for Congressional election discussion.
