Senator Arlen Specter (D-PA) raised over $1.1 million in the 4th quarter of 2009, and has over $8.6 million dollars cash in hand.
Specter is leading Democratic Congressman Joe Sestak in the Senatorial primary race and Sestak campaign officials are silent about their fundraising over the last quarter.
Sestak himself has complained that he is a lifelong Democrat and his party is not helping him enough in his battle with Specter, who was a Republican for decades.
When Specter switched parties, national Democrats assured him that they would help him in his re-election battle.
Specter may end up needing a serious war chest as well. The five-term Senator, who converted to the Democratic party last spring, has trailed Republican Pat Toomey in numerous polls over the past few months.
Many political insiders now consider the race a tossup, seeing former Republican Congressman Pat Toomey as a serious threat.
When Specter switched parties last spring, he admitted that he was facing an uphill fight in the Republican primary and cited that as one of the reasons for his decision.
As Fox first reported, Toomey raised $1.67 million in the fourth quarter of 2009, and has $2.8 million cash on hand going into 2010.
