With just hours before New Hampshire begins voting, Rubio looked dead on his feet, delivering the “low-energy” performance Trump has so effectively attached to Jeb Bush. Standing at a lectern at BAE System’s headquarters Monday morning, Rubio was every bit the junior senator, giving a subdued speech on national defense and the state of play in the Middle East.

“We face a critical moment,” Rubio told a group of more than two-dozen BAE employees. “I tell anyone who will listen, 2016 will be a turning point for America.”…

Rubio spokesman Alex Conant said they are ready for New Hampshire and beyond.

“While New Hampshire is ‘must win’ for several campaigns, we just want to finish in the top tier,” Conant said. “Our campaign is built for the long haul — as other candidates drop out after New Hampshire, the party will continue to unite behind Marco.”
