Rep. Michele Bachmann (R-Minn.) raised more than $2 million in the two and a half weeks since she announced her candidacy and has $4 million cash on hand after a $2 million transfer from her House account, according to CBS News.

Bachmann's fundraising prowess is only the latest good sign for the Minnesotan. Polls show her leading the pack in early-voting Iowa, where she grew up, and she has also gained in New Hampshire, the second state to cast its ballots.

The congresswoman has strong appeal to the social conservatives and evangelicals who are influential in Iowa's caucuses, and has close ties to the Tea Party.

Bachmann's totals surpass most other candidates'. But former Massachusetts Republican Gov. Mitt Romney reported last week that he had raised more than $18 million for the race and has $12.6 million cash on hand.
