Republican presidential hopeful Chris Christie warned that rival Marco RubioMarco RubioOvernight Defense: Commander calls North Korea crisis 'worst' he's seen | Trump signs VA order | Dems push Trump to fill national security posts What’s with Trump’s spelling mistakes?

Christie asked the audience Wednesday at a New Hampshire town hall.
"She will clean our clock. She will take every vote Rubio missed and she will feed it to him for lunch. ... What are we doing here? Let's be smart."
Rubio's critics have repeatedly piled on him for posting the worst voting record in the Senate, accusing him of skipping out on his responsibilities. But Rubio has fought back and argued that his presidential bid is for the greater good and that Senate votes will matter more when he becomes president.
Christie, the governor of New Jersey, has staked his bid on a strong performance in the New Hampshire primary, having made 179 campaign stops in the state, just one fewer than Ohio Gov. John Kasich had made, according to the New England Cable News candidate tracker
Despite a late surge at the end of 2015 in the state, Christie remains locked in a logjam of more moderate candidates who have all pegged their hopes on the Granite State.

Both Kasich and former Florida Gov. Jeb Bush are ahead of Christie, and Rubio's strong third-place finish in Iowa has given him a jolt of momentum heading into New Hampshire.
Like Kasich and Bush, Christie has kept Rubio square in his sights as he looks to climb back up the ladder and emerge as the establishment favorite.
He also turned his focus on Wednesday onto the Democratic field, promising to beat Clinton's "rear end" during general election debates.
"The last person she wants to see on that debate stage? You're looking at him. You know why? She's been running away from federal prosecutors for the last six months," Christie, a former federal prosecutor, said.
"I'll beat her rear end on that stage, and you know what? After I do, she'll be relieved because she'll just be worried I was going to serve her with a subpoena."
He also accused Clinton and Democratic rival Bernie SandersBernie SandersNRA head: Sanders 'a political predator' What would Bernie say to Wall Street for 0K?

The New Jersey governor told the audience about a time his mother took him to the supermarket as a child. The young Christie, he said, kept asking his mother if he could buy things from the shelves, to which his mother told him he could only if he was able to harvest money from the family "money tree."
"You're the money tree" to Democrats, he told the audience.
"You are a hardworking taxpayer in this country, they don't view you as human beings, they view you as the money tree."
He went onto directly target Clinton, telling the audience that none of her proposals are truly free.
"She's not going to give it to you for free, she's going to do one of two things: She's going to raise your taxes or borrow money from the Chinese," he said.
"There are two different philosophies in this campaign — I believe in you, she believes in government."
