Sarah Palin says Donald TrumpDonald John TrumpIG investigating Comey memos over classified information: report Overnight Defense: Congress poised for busy week on nominations, defense bill | Trump to deliver Naval Academy commencement speech | Trump administration appeals decision to block suspected combatant's transfer Top Pruitt aid requested backdate to resignation letter: report MORE should have showed more of his "conservative side," a day after he came in second in the Iowa caucuses.

“I think he just had to have seen more of his conservative side out, because Iowa’s so good and conservative," Palin told Yahoo News on Tuesday.

Polls had shown Trump ahead in Iowa, but Sen. Ted Cruz (R-Texas) pulled a surprise victory in the GOP caucus on Monday night. Cruz had 27.6 percent, followed by Trump at 24.3.

Palin, the GOP's 2008 vice presidential nominee, endorsed Trump earlier this month, delivering a boost to the outside candidate's bid.

Palin told Yahoo that she hasn't discussed joining Trump's ticket as a running mate.

 “I’ve not asked for a thing [and] he’s not promised a thing,” the former Alaska governor said. "There’s been absolutely no discussion about any kind of future whatsoever [and] all that speculative stuff, no.”

Asked if he would rebound in New Hampshire's primary on Tuesday, Palin said "I think so."

"He’s going to do well there" she added.

Palin was asked if Trump would have done better if she spent more time on the trail with him in Iowa.

"That's so nice," she responded.

The candidates are now headed to New Hampshire, where pre-Iowa polls showed Trump ahead of Cruz.
