Thompson announced his second quarter fundraising results Tuesday.
Former Wisconsin Gov. Tommy Thompson’s campaign announced raising $473,126 in the last three months, an increase over the $315,000 he raised in the first quarter of 2007.
“We are certainly pleased at the strong growth in our fundraising," Thompson said in a statement. "We've kept our overhead low and maintained a disciplined budget. To date, we're able to run a campaign equal to that of the better funded candidates despite the differences in funding."
Thompson did not reveal how much cash he had available as June 30.
All presidential candidates must submit detailed fundraising and spending reports to the Federal Election Commission by July 15.
