In the Senate, Democrats hold the majority and can be far more effective at driving Obama's legislative agenda. But a unified Democratic caucus in the House is critical on issues that might divide Republicans, such as an overhaul of immigration laws or even some fiscal policies.
Obama appears eager to work to strengthen the Democrats' hand.
Democratic officials said Thursday that Obama plans to headline at least 14 fundraisers this year for the party's House and Senate candidates. Vice President Joe Biden and Michelle Obama will also have a robust campaign schedule on behalf of Democratic candidates.
As he wrapped up his remarks to Democrats on Thursday, Obama left them with a hopeful thought: "I would expect that Nancy Pelosi is going to be speaker again pretty soon."
