U.S. Sen. Tammy Baldwin raised $2.5 million during the second quarter of the year and finished June with $3.9 million in the bank, her campaign said today.

Between Jan. 1 and June 30, Baldwin raised $4.7 million for her re-election bid, which her campaign said was the best first six months of an off year for a statewide candidate in Wisconsin, including those running for governor.

Baldwin’s campaign did not release how much she spent between April 1 and June 30, the most recent reporting period. But she finished March with $2.5 million in the bank, meaning she banked about $1.4 million of the $2.5 million she raised.

Baldwin’s campaign released her fundraising totals the same day Gov. Scott Walker’s campaign publicized the $3.5 million he raised over the first six months of the year. As a gubernatorial candidate, Walker is limited to individual contributions of $20,000, while Baldwin is restricted as a federal candidate to individual donations of $2,700 for the primary and another $2,700 for the general election.

Neither campaign has released their full reports from the latest periods to determine how much of what they raised was from individuals vs. committees.
