Washington (CNN) - President Barack Obama will host a webcast townhall Tuesday night, in the latest bid by party leaders to motivate Democrats to vote in the midterm elections.
The president will travel a few blocks from the White House to George Washington University, to headline a "Moving America Forward" town hall sponsored by the Democratic National Committee.
DNC spokeswoman Lynda Tran says the president will take questions from the estimated 125 people in attendance, as well as through Facebook, Twitter and what the party touts as the first time ever use of Skype in such a setting. The event will be live-streamed on http://www.barackobama.com/live.
The DNC says there will be hundreds of party supporters who will host house parties across the country to watch the event and to "engage" their friends and neighbors to vote in the November elections.
DNC Chairman Tim Kaine, the former Virginia governor, is expected to join the town hall via satellite from a watch party in New Hampshire.
This is the third DNC event in the past two weeks that the president has headlined. He was the main attraction at a party rally at the University of Wisconsin in Madison on Sept. 28 and he headlined a similar DNC event Sunday in Philadelphia. Later this week, Obama will take part in a town hall being broadcast on MTV, BET and CMT. And next week, the president is the main attraction at another DNC rally in Las Vegas, Nevada.
Polls suggest that the Democrats are facing an enthusiasm gap. Accruing to a CNN/Opinion Research Corporation national survey released Friday, most Republicans say they are extremely or very enthusiastic about voting this year, but only a third of Democrats feel the same way.
