This morning on "This Week," House Democratic Leader Nancy Pelosi, D-Calif., said the website glitches around the rollout of the president's signature health care law were "unacceptable."

"As far as the Affordable Care Act, as I call it, the fact is, that yes what has happened is unacceptable in terms of the glitches," Pelosi told ABC's Martha Raddatz on "This Week."

"This has to be fixed, but what doesn't have to be fixed is the fact that tens of millions of more people will have access to affordable, quality health care. That no longer having a preexisting medical condition will bar you from getting affordable care," Pelosi added.

Raddatz also asked Pelosi about former Secretary of State Hillary Clinton's political future, following her return to the campaign trail Saturday for friend Terry McAuliffe's Virginia governor's campaign.

Pelosi said she believes if Clinton does run for president in 2016, she would win and would be "a great president."

"Let me say, if Hillary Clinton does run, she'll be one of the best prepared people and she will win, I believe, if she runs," Pelosi said. "She'll be one of the best prepared people to enter the White House in a long time."

"She would be a great president. It would be a very thrilling thing for our country. She happens to be a woman, but she's first and foremost, extremely qualified," Pelosi added.
