House Minority Leader Nancy Pelosi (D-CA) defended her leadership on Sunday, resisting calls for her and the other senior Democrats to step aside for a new generation of party leaders.

Speaking to ABC's George Stephanopoulos, Pelosi said she has the support of her caucus, and she echoed statements she made earlier this year when she dubbed herself a "master legislator."

"She's also a master at losing House seats for Democrats, which is what we've seen under her leadership," Lisa Boothe remarked on "Outnumbered."

Boothe said it was particularly glaring in Georgia's special election between Democrat Jon Ossoff and Republican Karen Handel. Handel repeatedly highlighted Ossoff's ties to Pelosi and said a vote for him would be a vote for the House minority leader. Handel won the election, and many blamed Ossoff's loss in part on Pelosi.

Former Utah Congressman Jason Chaffetz (R) said as long as Democrats have leaders like Pelosi and Senate Minority Leader Chuck Schumer, they will continue to lose.

He pointed out that since former President Obama first took office, Democrats have lost 900 seats, including governors, state legislators, senators and representatives.

"They've got a long way to go. This is a conservative nation. Republicans are doing well. But now that they have the levers of control, they have to produce," Chaffetz said. "They produce, and they'll continue to have Republican majorities."
