Sen. Arlen Specter, D-Pa., raised $1.16 million in the first quarter of 2010 and has $9 million in cash on hand.
However, that was less than half of the $2.3 million his Republican challenger Pat Toomey raked in during the same time period.
Specter, the incumbent Democrat still maintains a serious cash-on-hand advantage with $9.06 million in his warchest, while Toomey reported just over $4 million.
However, Specter is beginning to spend money in his Democratic primary fight with Rep. Joe Sestak.
Sestak has not announced his first quarter fundraising numbers, however he has long complained about the difficulties of fundraising while being abandoned by the Democratic establishment.
Last spring when Specter bolted the Republican party, President Obama assured him White House support.
Sestak has since been openly bitter about national Democrats supporting Specter, a man who Sestak points out was a lifelong Republican until last year.
Specter’s quarterly fundraising totals have been in decline ever since he switched parties.
The Pennsylvania senator raised $1.92 million in the third quarter of 2009 and $1.15 million in the fourth quarter, before posting his latest, $1.16 million haul.
