Obama, Jim Messina to keynote Senate Dem conference

President Obama and Jim Messina, his reelection campaign's manager, will headline the Senate Democratic retreat Wednesday, according to a senior Democratic aide. 

The annual strategy planning and policy conference will take place at Nationals Park in Washington, D.C.

In late January Obama was the speaker at the House Democrats' conference in Cambridge, Md. Obama's speech centered around raising optimism among House Democrats. He predicted that House Minority Leader Nancy Pelosi (D-Calif.) would regain her former seat as House Speaker.

Obama and Messina's appearance will come 48 hours after Messina announced that the Obama reelection campaign would encourage donors to give to the pro-Obama super-PAC Priorities USA, a Democratic political action committee.

Obama's reelection campaign said it had decided to embrace the super-PAC because political action committees for Mitt Romney and other Republican presidential candidates have proved influential in the 2012 presidential race thus far.
