House Democrats who voted for a Republican bill to change Obamacare were politically motivated, according to House Minority Leader Nancy Pelosi, D-Calif., who said that implementing the health care law is more important than "who gets re-elected."

"And this is an issue that has to be dealt with, but it doesn't mean, 'Oh, it's a political issue, so we're going to run away from it,' " Pelosi said of the idea that Obamacare's problems could cause Democrats to lose seats in Congress.

"No, it's too valuable for the American people. What is important about it is that the American people are well served, not who gets re-elected," she told NBC's David Gregory on "Meet the Press."

She said that the 39 House Democrats who supported a Republican measure that would "sabotage" Obamacare, according to President Obama's spokesman, were just posturing.

"When the Republicans put forth a political initiative, people respond to it politically," Pelosi said. "[A]s to my members, however they voted on this — this is political. They respond politically."

House Democrats lost 63 seats in the 2010 midterm elections after then-Speaker Pelosi led her caucus to pass Obamacare.

"[Y]ou can't be knocked for a loop just because somebody's playing politics," she told Gregory. "If that was the case, we would have never passed it in the first place."
