The Virginia Tea Party Alliance’s political action committee will begin airing a TV ad Monday targeting Senate Democratic candidates in vote-rich Northern Virginia.

The ad ties seven Democrats to President Barack Obama, accusing them of supporting “Obamacare,” “in-state tuition for illegals” and more programs, regulations and taxes.

“Say no to Obama. Say no to the Virginia Obama Democrats,’’ the narrator says.

It praises tea party favorite Attorney General Ken Cuccinelli (R) of standing up to Obama’s “radical leftist agenda” and singles out six Democratic senators — Sen. George Barker (Fairfax), Toddy Puller (Fairfax), Mark Herring (Loudoun), Chap Petersen (Fairfax), Charles Colgan (Prince William) — and two candidates — Barbara Favola in Arlington County and Shawn Mitchell in Prince William and Loudoun counties.

“Each of these candidates has promoted and endorsed President Obama’s policies in the Virginia state Senate,” said Karen Miner Hurd, executive director for the alliance. “The implementation of programs like Obamacare would be devastating to Virginia’s budget and our economy. They need to be held accountable for their support of the president’s destructive policies like Obamacare and extreme environmental regulation by the EPA.”

It is the tea party’s first TV buy in Virginia, though it has run radio ads in three senate districts — those held by Democratic Sens. Ralph Northam (Norfolk), Roscoe Reynold (Franklin) and Phillip Puckett (Russell).

In September, the alliance announced it would target seven “left-wing” Democrats as the group hopes to help Republicans take back control of the Senate.

Virginia Republicans are aggressively challenging Democrats’ hold on the Senate in part by tying them to the president.

The Republican Party of Virginia has sent out more than a half-dozen e-mails about Obama since mid-September, many with the word “Panic!” in the headline. Two weeks ago, the party announced the “Proud to Stand with Obama” direct mail scavenger hunt in which people were urged to try to find a Democratic direct mail piece that uses a picture of Obama in a positive light.
