— Nine candidates took the stage here Tuesday night for the final primetime Republican debate of 2015, but in critical moments it seemed there were only two: Ted Cruz and Marco Rubio.
The pair of freshmen senators went toe-to-toe several times, most notably on the issues of the National Security Agency’s data collection and immigration, participating in lengthy back-and-forth exchanges that left the other candidates sidelined while CNN featured the budding rivals in a split-screen presentation.
Tuesday may have foreshadowed a Rubio-Cruz battle for the nomination that more and more Republicans are now predicting, as Cruz continues to consolidate the support of conservative voters and Rubio emerges as the favorite of center-right, establishment-oriented voters. The headlines coming out of the Nevada debate could further cement the narrative of a collision course for the two senators, who presently occupy very different places in the Republican field. Rubio, despite strong debate performances, remains stuck in the mid-teens in early-state polling; Cruz this week surged to the top of several Iowa surveys and is gaining momentum nationally.
The looming threat to such a binary battle continues to be Donald Trump, who continues to place at or near the top of virtually every poll in the early nominating states. But the bombastic real-estate mogul was largely absent from the defining moments of Tuesday night’s debate inside the towering Venetian hotel and casino here on the famed Las Vegas strip.
The first direct conflict in the suddenly fierce rivalry between Senate colleagues, heretofore conducted via dueling press releases, came when co-moderator Dana Bash asked Rubio about Cruz’s support for a bill that limited the NSA’s ability to collect metadata from US citizens.
“Is Senator Cruz wrong?” Bash asked Rubio, who voted against the bill. “He is,” replied Rubio. “And so are those who voted for it.” His campaign fleshed out the jab hidden in those words with a press release showing Cruz surrounded by other senators who voted for the bill: Democrats Harry Reid, Chuck Schumer, Al Franken, and Barbara Boxer.
