Our chances for the two Connecticut seats aren't that great, we blew our chance in 2004 (although personally I would have voted for both Simmons and Shays, and probably Johnson as well) with Kerry and Dodd on the ticket. In 2006, any Lieberman effect will be cancelled out by Rell being on the top of the ticket. I doubt we can pick up any CT seats in 2006, 2008-maybe.
Ticket spliting between federal and state races is pretty common. Almost every heavily Democratic state currently has a GOP governor.
