As in Iowa, you can’t help but notice the enthusiasm gap between Republicans and Democrats. This morning Obama drew 3,000 people and no one seemed to mind the event starting an hour late or that a large chunk of the audience had to be located in an overflow room. The majority of the crowd were families with young kids: political pay dirt. There were only 600 people at McCain’s event. Admittedly it was in a much smaller town and there were more people waiting outside, but unlike at Obama’s most of McCain’s attendees were older voters—the average age must have been comfortably over fifty. If you're a Republican you have to worry about how fired up the Democratic voters are and just how many independents Obama is bringing to the party.
