Under Pressure After Debate, Bush Insists He's Not Dead Yet

One candidate came out of Wednesday night's Republican presidential debate with a lot of questions to answer — Jeb Bush.

Supporters were disappointed by his performance and inability to stand out at a critical time for his campaign. As Bush struggles, his chances may come down to the early primary state of New Hampshire.

Bush had a big moment preplanned in that Colorado debate. It was aimed at Sen. Marco Rubio, R-Fla., for missing so many votes in the Senate while campaigning.

"Marco, when you signed up for this, this was a six-year term, and you should be showing up to work," Bush said. "I mean, literally, the Senate. What is it, like a French work week? You get like three days where you have to show up? You can campaign — or just resign and let someone else take the job."

Rubio was ready. He referenced the 2008 campaign of John McCain, who also missed votes in the Senate.

"I don't remember you ever complaining about John McCain's vote record," Rubio quipped. "The only reason why you're doing it now is because we're running for the same position, and someone has convinced you that attacking me is going to help you."
