State Sen. Dina Titus (D), who decided just before the Silver State’s May filing deadline to challenge Rep. Jon Porter (R) in the suburban Las Vegas 3rd district, raised $575,000 by late June, according to a campaign press release on Wednesday.

“I am so honored to receive this substantial support in the two months since I announced my candidacy,” Titus said in the release. “People want a change, and I am running for Congress to be a strong independent voice for families in Congressional District 3 struggling to make ends meet.”

Porter’s second-quarter numbers have not been released yet, but at the end of March he had raised more than $1.6 million this cycle and had more than $1 million in cash on hand.

The Titus-Porter matchup is expected to be one of the most closely watched races in the country with the Democratic Congressional Campaign Committee putting its full weight behind the state Senate Minority Leader, who is coming off a failed 2006 gubernatorial race. The DCCC has placed Titus in its “Red to Blue” fundraising and infrastructure program, and she will also be the beneficiary of a DCCC combined campaign account created specifically for top women candidates across the country.
