Rep. Roy Blunt (R-Mo.) boasted Thursday of raising $2.2 million for his Senate run in the last quarter, besting his Democratic opponent, Missouri Secretary of State Robin Carnahan, by almost $700,000.

Blunt's camp made the announcement first via Twitter, calling it his "largest quarter of the campaign."

Soon after, the campaign blasted a release to reporters noting it had more than $4.5 million cash on hand. Blunt received money from 5,000 individual donors in the second quarter. It's also spent almost $1.1 million since March 31, according to its disclosure report.

Carnahan, meanwhile, had her "best quarter to date."

She raised $1.55 million from 30,000 donors and now has $3.63 million banked, according to her campaign. She had a lower burn rate, spending $760,029 in the last three months.

Blunt spokesman Rich Chrismer said their fundraising figures are a sign that Missouri voters are rejecting Democratic policies.

"It is so clear to a huge and growing number of Missourians that the Carnahan, Pelosi, Reid and Obama policies are a disaster for jobs, the economy, healthcare and energy," Chrismer said in a statement.

A Carnahan spokesman said voters have had "enough" of Blunt.

"Missourians have had enough of Congressman Blunt's 14 years of wasteful spending in Washington and that is why he has been forced to go on TV early in the closing weeks of his primary fight to defend his record of bailouts, earmarks, and deficit spending," Carnahan spokesman Linden Zakula said in a statement.
