Cruz campaign: We could have stopped Trump if Rubio became running mate

Politico reported in March that Rubio rejected the idea of a “unity ticket.” But the sources close to Cruz and Rubio are now offering a much fuller picture of the extent of Cruz’s polling, the reasons why Rubio said no, and the resentment the Cruz people have about Rubio’s rejection of the idea.

The Cruz campaign polled in three March 15 primary states, Illinois, Missouri and North Carolina — though not in Ohio, home to Kasich, or in Florida.

They also tested the matchup in a poll in Arizona, which would hold its contest on March 22, and in Wisconsin, which would hold its primary on April 5.

What did polls suggest a Cruz-Rubio ticket would do in those states?

“Blowout,” said a source close to Cruz. “65%-35%,” with Trump losing.
