WASHINGTON (CNN) - A little more than a week after President Obama pledged to "call out" opponents who make what he calls irresponsible arguments about his health care plan, the Democratic National Committee launched a tough new campaign to push back against GOP critics.
The DNC is asking supporters to pressure individual foes of the president's plan via phone and social networking sites like Facebook and Twitter. Democrats are also launching an online "action center."
"Every Republican official must understand: If you lie about reform, the American people will call you out!" DNC Executive Director Jennifer O'Malley Dillon told supporters in a Friday e-mail.
First in the crosshairs: Republican Gov. Tim Pawlenty of Minnesota, who has taken an increasingly high-profile national role this year. The DNC's Friday e-mail asked Democrats to call his office to complain about recent comments over the controversial "death panels" debate, and to take a new Web video slamming the Minnesota governor viral.
The DNC also released a one-minute TV ad, its latest outreach effort to a liberal base unsettled by reports the administration would consider swapping a public option for a "trigger" provision in any health care bill, in a bid to win the support of Republican Sen. Olympia Snowe.
"Fired Up, Ready to Go" - which features President Obama addressing University of Maryland students Thursday - will run on national cable in the Washington, D.C. area starting Monday. The spot will also be placed on key national and local liberal blogs.
