Washington (CNN) - Pennsylvania Senate hopeful Pat Toomey raised $2.3 million in the first three months of 2010, and has more than $4 million cash on hand, his campaign said Monday.
The former Republican congressman is aiming to unseat five-term Sen. Arlen Specter, who switched from the Republican to Democratic party last spring in part because he did not want to face Toomey in a primary challenge.
"I am very appreciative of the deluge of support I have received for my candidacy," Toomey said in a written statement. "As I travel across the state, I meet more and more Pennsylvanians who want to join our campaign and help bring true change and fiscal sanity to Washington.
Official fundraising totals for the first quarter of 2010 are due April 15, but the early release suggests Toomey believes he has amassed enough of a war chest to mount a vigorous campaign.
Specter will have to defeat challenger Rep. Joe Sestak in the Democratic primary before facing Toomey, the presumptive Republican nominee.
A Franklin and Marshall College survey released March 24 indicates that a hypothetical race between Toomey and Specter is essentially tied, with Toomey's slight advantage falling within the poll's margin of error.
