There are more Republicans who are 'very excited'- 62% to the Democrats' 57%, but 'somewhat excited' voters are going to come out the vast majority of the time. The ones you need to worry about are the 'not excited' voters- and 18% of Republicans and 16% of Democrats fall into that category, virtually indistinguishable.
Digging deeper the single group with the highest percentage of voters who are 'very excited' about turning out next year is African Americans at 71%. Anyone who thinks black voters aren't going to match their record turnout from 2008 and cast more than 90% of their votes for the President is kidding themselves. They may not have been excited enough about the Dan Onoratos and Brad Ellsworths and Jon Corzines of the world to turn out in 2009 and 2010 but that says nothing about their eagerness to come out with Obama back on the top of the ticket.
Another big turnout issue for Democrats last year was that the percentage of voters under 30 collapsed while the share over 65 collapsed. That also doesn't look like it will be a problem next year- the 54% of young people 'very excited' about voting next year is exactly the same as the portion of senior citizens who express that sentiment."
