The race is reminiscent of several such races among Rs in 2005 and early 2006 that were the first signs of possible trouble for the Rs. Seats that should have been much safer winning by narrow margins.
Jim Ogonowski, the R candidate, appears to have done well from immigration, but ultimately could not overcome identification with George Bush -- particularly the SCHIP veto and overall handling of the Iraq War. But the lack of enthusiasm for Tsongas should send a warning to Ds that they can, indeed, blow it in '08 unless they get their act together. And, between you and me, I'm not convinced Clinton would carry the 5th District of MA.
