Dear Republicans, It's Ted Cruz

What is the rationale for Marco Rubio’s candidacy?

The latest poll out from the classiest and most reliable Florida pollster, Quinnipiac University, says there is none.

After a week of disappointing elections for Rubio, the Florida Q Poll is the dagger to the heart of his presidential aspirations. Former Florida Gov. Jeb Bush can be happy that while his own bid failed, at least he killed the one his campaign staff called "Judas." Enjoy Fisher Island.

The poll shows frontrunner Donald Trump doubling up Florida freshman Rubio with less than a week to go before the winner-take-all contest for 99 delegates. Coming after a disastrous election night it should be enough to send Rubio packing.

The only argument for Rubio’s continued candidacy was the “Romney Plan” in which voters should support any candidate in any race that can beat Donald Trump or deny him delegates. It worked pretty well in Michigan where Sen. Ted Cruz, R-Texas and Ohio Gov. John Kasich soaked up the majority of delegates with their tie for second place behind Trump.

But there is no hope that Rubio can be the guy to stop Trump in Florida anymore. While Republicans have resisted Cruz, despite his repeated successes, it may be time for the party to admit that Sen. Lindsey Graham, R-S.C., is quite right: Cruz is the only candidate who has any shot of denying Trump the nomination.

While there was a wintertime flirtation with Trump as the more establishment-friendly and malleable candidate for the GOP, springtime has brought a new realization that Trump could mean not just a general election wipeout, but also generational damage to the party’s brand. Cruz has never been the GOP’s dream date, but if he can beat Trump it may be enough.
