Washington (CNN) - Though Republican Sen. Olympia Snowe hasn't drawn a Democratic challenger yet, she's plenty prepared for a re-election battle. According to fundraising numbers for the first quarter released Monday, Maine's third term senator has over $2 million in cash on hand.
Snowe raised $877,019 in the first quarter of 2011 and spent $62,433 on her 2012 U.S. Senate campaign. She will report $2,050,053 in cash on hand 17 months before the Senate election, according to numbers released by her office.
Snowe for Senate Treasurer Rick Bennett said, "It's a good start for her campaign fundraising effort. The total raised really signals how seriously committed she is and her supporters are to this race."
"The campaign needs to be prepared to tackle any challenges," he continued.
Challenges will come as early as the Senate primary for Snowe, who has been criticized within her party for not being conservative enough. Among her alleged offenses: early support of health care reform, though she voted "no" in the final floor vote.
Two Tea Party challengers have announced bids to unseat Sen. Snowe in February: Andrew Ian Dodge, former state coordinator for Maine's Tea Party Patriots, and Scott D'Amboise, a business owner supported by the Maine Tea Party.
Dodge, a freelance writer who called Snowe "almost as bad as Obama" and accused her of selling out the Republican Party, did not respond to requests for information on his campaign fundraising totals. D'Amboise also could not be reached for comment.
The deadline for filing federal campaign finance reports for the quarter ending March 31 is on Friday.
