Democrats are looking to a pair of comedians, Jon Stewart and Stephen Colbert,  to do what President Barack Obama, former President Bill Clinton and dozens of other Democrat leaders haven’t done yet this election season: Get someone other than Republicans excited about voting. 

Stewart and Colbert expect tens of thousands of fans to join them three days from now at the “Rally to Restore Sanity”, the progressive alternative to the various conservative "Tea Party" rallies held this year.
 
The president will appear on “The Daily Show” tonight and he knows those viewers are already Democrats - he is just hoping he can get them to go to the polls despite their waning enthusiasm for his performance almost halfway through his term.
