LOS ANGELES (KTLA) -- Republican presidential candidate Newt Gingrich continues his fundraising campaign in Los Angeles Tuesday.

The former House speaker will visit the Tulare World AG Expo, in addition to holding private fundraisers.

Gingrich is on a fundraising spree for conservative cash in California.

At a Pasadena TeaPAC event on Monday, he promised more oil drilling, and even took aim at the L.A. Unified School District.

"As long as you have places like L.A. Unified where the teachers' union is more concerned about protecting bad teachers than they are about the students, you have a huge crisis," Gingrich said.

He also spoke at a Hispanic leadership even in South El Monte on Monday, but never mentioned his rivals, Rick Santorum and Mitt Romney.

Gingrich insisted he was sticking to talking about himself and what he believes is important to Californians.

"My big message is going to be more jobs and lower gas prices," the candidate told KTLA. "I think in California that should work reasonably well."

His visit comes as the National Review, a conservative publication, released this scathing opinion about Gingrich:

"It would be a grave mistake for the party to make someone with such poor judgment and persistent unpopularity its presidential nominee."

"I ignore them," Gingrich told KTLA, saying the National Review "for a long time has been an insider establishment group."

Gingrich hasn't had a win since South Carolina. Romney, meantime, won Maine on Saturday, and Santorum is seeing a surge after his three back-to-back wins.

The latest poll by American Research Group has Santorum leading Romney by six percent in Michigan -- the next primary, and Romney's home state.

"Last Monday you would have said, what should Rick Santorum do? He came in fourth for three primaries in a row," Gingrich said.

"He had a good Tuesday. Now he's the flavor of the week."
