Pataki on Uber: My Most Used App Since I'm No Longer Governor

Former New York Gov. George Pataki admits he misses having a driver like he did during his days in the governor's mansion.

During Wednesday's GOP presidential debate, the four undercard candidates were asked what apps on their smartphones they use most. Pataki quickly said Uber, the app that brings a driver to pick you up.

"When I was governor I had a driver. I don't anymore," Pataki said. "And it's an example of what millennials are doing to change America for the better. And I tweet a lot, too."

Louisiana Gov. Bobby Jindal said he still has a BlackBerry, so no apps for him. "I basically use if for scheduling. I use it to keep up with my wife … my three kids," he said. "I use it to keep up with the news on the Internet."

Rick Santorum was quick and to the point: MLB, NHL and The Wall Street Journal.

Lindsey Graham drew laughs when he said, "Well, No. 1, the only reason I have an iPhone is because I gave my number to Donald Trump. Don't do that."

Trump released Graham's old cell phone number (to his flip phone) after Graham criticized him for saying his friend Sen. John McCain was not a war hero.

When Graham did share his top app it didn't go over well with the CNBC moderators.

 "No. 1: Fox News," Graham said, quickly adding, "Sorry about CNBC. We're at a Republican primary here."

"Thanks, thanks a lot," moderator Carl Quintanilla said.

"We take your time back," moderator Becky Quick added.
