Of the 54 Blue Dog in the House, six have retired, 39 are in competitive races, and 22 of those are in pure toss-ups, according tot he Cook Political Report. Blue Dogs are Democrats from the conservative districts, which says one expert makes them an endangered species anyway. The result will be that the returning Congress will have Democrats who are more liberal than the previous Congress. The same dynamc is being repeated on the Republican side with some 50 newcomers expected, and they are not from the political centre. This will make for a very polarized Congress, with less opportunity for new legislation in areas where it is needed.
