As they rise together in national polls, Marco Rubio and Ted Cruz are seeking ways to use each other to break away from the pack and ultimately stand alone.
With Donald Trump still leading in national and early state polls and Ben Carson fading, the spotlight is on the number two spot in the race for the GOP presidential nomination. While each is competing in his own lane — Cruz as the conservative consolidator and Rubio as the establishment’s consensus candidate — each has a vested interest in exploiting the other’s vulnerabilities.
Cruz has made significant strides on his way to becoming conservatives’ choice, as would-be rivals for this segment, including Mike Huckabee, Rick Santorum, Bobby Jindal and Scott Walker, have either failed to gain traction or dropped out of the race all together.
