BEDFORD, N.H. (AP) — Marco Rubio's uneven debate performance just days before Tuesday's New Hampshire primary has emboldened a trio of governors seeking to stem his rise in the Republican race for president.

But if Rubio's rivals can slow him in New Hampshire, they are likely to leave the GOP with a muddled mix of establishment contenders and no clear favorite to challenge Donald Trump and Ted Cruz.

At the heart of the battle between Rubio and Chris Christie, John Kasich and Jeb Bush is whether the freshman Florida senator has the experience and policy depth to serve as president.

Christie unleashed withering attacks against Rubio in Saturday's debate, and the New Jersey governor tripped up Rubio by calling him out in real-time for his reliance on rehearsed talking points.
