ABC News’ Devin Dwyer reports: Christine O’Donnell, Delaware’s GOP U.S. Senate candidate, broke her week-long silence in the national media this morning calling party leaders’ approach to the Democrats’ health care reform law “lazy.” “You’re hearing this cop-out excuse that we can’t repeal Obamacare as long as Obama is in office,” she told conservative Baltimore talk radio host Tom Marr. “That is simply not true. That’s a lazy approach to dealing with this.” Senate Minority Leader Mitch McConnell, who favors a repeal, has acknowledged it would be near impossible to do: “Without the president, we can’t repeal it,” he said in December. “But we can go after portions of it aggressively.” House Minority Leader John Boehner, also an outspoken proponent of repeal, refused to use the word when pressed on the question by reporters last week. “I am committed to doing everything that I can do and our team can do to prevent ‘Obamacare’ from being implemented,” he said. Still, O’Donnell believes when there’s a will, there’s a way — and that Republicans could effectively put President Obama at risk of an intraparty challenge for the nomination in 2012. “If the House and the Senate both pass a bill to repeal Obamacare, and the year before Obama’s reelection he dares to veto it, he dares to thumb his nose to the will of the people, he’s setting himself up to be very vulnerable to a primary challenger,” she said. A poll by the Kaiser Family Foundation released earlier this month shows only 26 percent of Americans say the law should be repealed as soon as possible, however.

O’Donnell’s appearance on Marr’s show comes one week after she told Fox News’ Sean Hannity that she would be limiting her media exposure. “She’s been relatively hard to get a hold of,” Marr said before introducing her on the show. ”I apologize, it’s been a little busy over here,” O’Donnell replied. “We were prepared for a transition to the general [election,] but we never anticipated how big this has exploded.” As of Friday, O’Donnell tweeted, her campaign has raised more than $2.5 million. A spokeswoman for her campaign reached by ABC News would not immediately provide details on the number and nature of O’Donnell’s public events with Delaware voters over the past week.
