Fox News contributor Karl Rove said Monday on "America's Newsroom" that Rep. Nancy Pelosi is "formidable" and likely to once again be elected House Speaker, which could signal trouble for some in her party.

A number of Democratic lawmakers who previously vowed not to vote for the California Democrat have recently changed their minds.

Rove said Pelosi is "twisting arms and breaking legs" to gain support for the speakership, which House Democrats will vote on this Wednesday before a January floor vote.

"There's no doubt she's formidable and she's likely to win," he said of Pelosi. "But at what price?"

Rove explained that it will be interesting to see how many of the Democrats that signed onto a letter opposing Pelosi will fold and change their minds.

"How are those people gonna go home and say, 'I told you I wouldn't do it, but I did it after my arm was twisted or my leg was broken,'" he said.

Although Rep. Marcia Fudge (Ohio) considered challenging Pelosi for the role, she decided to back her instead.

Rove said that Pelosi is a "tough character" and is backed by a strong group of liberal House members.

"She doesn't want to be a transitional figure," he said, adding that if the Democrats retake control of the White House in 2020, Pelosi would want to be Speaker like she was under Barack Obama.
