A political organization affiliated with the conservative advocacy group Citizens United has poured another $18,000 into state House and Senate races in Virginia , hoping Republican wins will send a message to President Obama that Virginia won’t go his way in 2012.

The contributions by The Presidential Coalition, Citizens United’s tax-exempt, political fund-raising affiliate, bring its totals to $96,250 in Virginia during the 2011 election cycle — “with more to come,” according to a news release announcing the donations Thursday.

“The Presidential Coalition has spent nearly $100,000 in Virginia this cycle because it is a very important state, not just in 2011, but in 2012 as well,” David N. Bossie, president of Citizens United, said in the release.

“If Republicans capture the Virginia Senate, it will send a clear message to the White House. Virginia is key to a President Obama victory in 2012, and by winning these state races in 2011, the Obama campaign will have an even steeper mountain to climb going forward.”

As the GOP tries to take control of the Senate, The Presidential Coalition contributed $2,500 apiece to candidates Dick Black, Miller Baker, Mickey Chohany and Bryce Reeves. Incumbent Sen. Jill Holtzman Vogel received $1,000.

The group donated $1,000 apiece to two incumbent delegates, Ron Villanueva and Jim LeMunyon. It also gave $5,000 to House Speaker William J. Howell’s Dominion Leadership Trust.

“It will set the stage for 2012, especially if the state Senate flips Republican,” Citizens United press secretary Jeff Marschner said in an interview.
