There is a very interesting look at potential Dem US House seat pickups in 2008 over at Political Truth. progressiveflademocrat gives a good rundown on some of the potential pickups. Vern Buchanan, Ric Keller and Tom Feeney (he of the newly minted legal defense fund) lead the list.
Also getting mention is Bill Young. There is the inevitable question about retirement. However, I firmly believe that Young will have to be carried out of the Capitol in a box. That does bring up a very interesting prospect however. Death in office requires a special election to be held. That could actually be very good news for the Dems. FL-10 is still a very tough proposition for any Democrat despite the Districts top of the ticket voting pattern. However, with a special election, FL-10 would likely get a ton of attention from the DCCC. This District would be hard pressed to ever get that kind of DCCC support in a regular election cycle.
Just some food for thought.
