According to MPR, the race between Michele Bachmann and Tarryl Clark has become the most expensive US House race in the country.

In election filings released last month, both Bachmann and Clark trotted out eye-popping strings of dollar signs.

By the end of the filing period in July, Bachmann had raised more than $4 million.

Meanwhile, Clark had pulled in about $2.4 million.

Bachmann campaign officials say they have raised another $2 million since then. Clark’s campaign declined to comment on how much they’ve pulled in since the July report.

Their fundraising has set records in Minnesota, and elsewhere.

“It is also the most prodigious campaign fundraising that we’ve seen in the country so far, which is a shocker, when you consider that the media market is not nearly as expensive as those in California, New York, and elsewhere,” said Larry Jacobs, a political science professor at the University of Minnesota.

Just wait ’til the TV ads begin.
