The party’s House and Senate fundraising arms closed out 2013 with big cash hauls bolstered by extensive fundraising commitments by President Barack Obama, First Lady Michelle Obama and Vice President Joe Biden.

On the outside group front, Senate Majority PAC and House Majority PAC have emerged as legitimate and well-funded rivals to conservative outside groups like Karl Rove’s Crossroads network and the House-focused Congressional Leadership Fund. Both groups on their own beat the entirety of Rove’s Crossroads network in 2013, according to fundraising numbers released Friday.

And unlike their GOP counterparts, Democratic Senate and House candidates are facing few serious, intraparty primary battles — allowing party organizations and Democratic outside groups to conserve cash stockpiles for the general election.

“In 2012, Democratic groups began working in concert with an unprecedented level of synchronicity,” said Bill Burton, a former White House aide who co-helmed the super PAC Priorities USA Action in 2012. “That harmony has given the donor community a real sense of confidence that the state of the Democratic infrastructure is strong.”
