On the trail

Gov. Chris Christie told New Hampshire voters that Republicans shouldn't make the same mistake Democrats made in 2008: electing an inexperienced one-term senator as president who isn't ready to lead. He said Sen. Marco Rubio and Sen. Ted Cruz "have never managed a thing. … To put a first-term U.S. senator back in office immediately after the last seven years we've just had is crazy. These guys are not ready."

Donald Trump told voters in Waterloo, Iowa, that evangelical Christians "really do get me. … They understand me better than anybody."

Gov. John Kasich said his rivals should follow his lead and call on the super PACs supporting them to take down negative advertisements. He said candidates should talk about "what they're for" rather than knocking one another down. His campaign on Monday told the super PAC backing him not to air a negative TV ad against rival Marco Rubio. Campaigns and super PACs are barred from coordinating, but the super PAC chose to replace the negative ad with a positive spot about Kasich.

Sen. Ted Cruz's proposal to carpet-bomb the Islamic State in Iraq and the Levant prompted criticism from the commander of military operations against ISIL. Army Lt. Gen. Sean MacFarland, who spoke from Iraq, said such strikes are "inconsistent with our values" as a nation. He said such indiscriminate bombing would kill innocent civilians as well as enemy combatants. But Cruz also won praise on Monday with Donald Trump calling him "a talented guy" and Marco Rubio saying Cruz "has a very strong ground game."

Former Alaska Gov. Sarah Palin said she has no regrets having endorsed Donald Trump for president over his rival Ted Cruz, whom she endorsed during his run for a seat in the U.S. Senate. Speaking to NBC's Today, Palin said of Cruz, "I want to keep him in the Senate and I want Donald Trump to be our president."
