President Obama’s reelection campaign slammed Mitt Romney during his Washington D.C. visit Wednesday, saying the GOP presidential candidate would “rubber stamp” current Republican legislation.

“Mitt Romney is heading to Capitol Hill today to make clear once again that he would rubber stamp the agenda of House Republicans,” Ben LaBolt, press secretary for the Obama campaign, said in a statement. “While the President is fighting to create jobs now and to restore economic security for the middle class, neither Mitt Romney nor the House Republicans have introduced a plan that would do so – instead they would shift a greater share of taxes away from large corporations and the wealthiest onto the backs of the middle class.”

The charges come as a CBS News/New York Times poll shows distrust of government is at its highest level ever. The poll found that 89 percent distrust government to do the right thing, 74 percent say the country is on the wrong track and that Congress has an 84 percent disapproval rating.

The Obama campaign has seemed to zero in on Romney as their main competitor in recent weeks ahead of the nomination process that won’t occur until next year. David Axelrod, Obama’s senior campaign adviser, has made multiple media appearances targeting Romney for criticism.

And Romney appeared to zero in on Obama. At a campaign appearance in Virginia, he was asked which of the other Republican presidential hopefuls he considers his main competition for the nomination.

“I think the biggest threat to my success is President Obama and I plan on beating him soon,” Romney said.

Romney was near Capitol Hill on Wednesday for a fundraiser luncheon located at the American Trucking Association headquarters, near the Republican National Committee building south of the Capitol. Several members of Congress were in attendance at the fundraiser, including House Oversight and Government Reform Chairman Darrell Issa (Calif.), Armed Services Committee Chairman Buck McKeon (Calif.), Intelligence Committee Chairman Mike Rogers (Mich.), Rep.

Earlier in the day, Romney visited a GOP volunteers in Fairfax County, Va., along with Gov. Bob McDonnell and Lieutenant Gov. Bill Bolling. 

“I’m just here to do my very best to encourage the people of Fairfax County,” Romney said at the event, which was in support of the Republican candidates in the upcoming Virginia legislative election.
