I understand Krugman's urging of Democrats to be more partisan, since he is a true, old school liberal. However, as a young voter, I am really tired of this fight. Any Democratic push to the left, even if it results in victory in 2008, would simply embolden the old school conservatives in 2010 and / or 2012, resulting in more disaster and partisanship. Seeing how Congressional Republicans behave now, imagine how difficult they could make politics for a partisan Democratic president a few years from now when they get their first sniff of blood. There are solutions to many of our problems that can be reached without the political gamesmanship that has decined politics since the 1960's. To me, the most successful executive politicians this decade have been Schwarzenegger and Bloomberg, both of whom are essentially non-partisan, socially liberal, economically moderate / conservative "Republicans" who work with and endorse politicians of all parties. Hate it or love it, this is the model we are moving towards and Obama is really the first presidential candidate we have seen with this type of outlook. 10 or 15 years from now, the Obamas of the world are going to dominate American politics...
