Ted Cruz has mouthed some vitriolic words against Mitt Romney in the course of the presidential campaign. The two Republicans are not exactly fond of each other. But, it seems like the two are willing to set aside the bad blood, albeit temporarily, in order to bring down a common foe, and a formidable one at that.

Romney announced he will vote for Cruz come Tuesday's caucuses in Utah. And, he is asking his supporters to do the same. Cruz, on the one hand, was quick to express his gratitude and said that he will take Romney's vote "happily."

Romney Urges Utah Voters to Rally Behind Ted Cruz

"This week, in the Utah nominating caucus, I will vote for Senator Ted Cruz," Romney posted on his Facebook account. The 2012 Republican nominee, while not endorsing Cruz per se, believes that the only way for Trump not to get the required number of delegates to secure the party's outright nomination is for Cruz to deny him as many delegates as possible in the remaining contests.

"I will vote for Senator Cruz and I encourage others to do so as well, so that we can have an open convention and nominate a Republican," he added.

Romney also cited the ongoing battle between Trump and the GOP, which he referred to as the "contest between Trumpism and Republicanism." He also expressed his disdain for what he claims have come to define Trump's campaign like racism, misogyny, bigotry, xenophobia, vulgarity, and threats and violence.

"I like Governor John Kasich. I have campaigned with him. He has a solid record as governor. I would have voted for him in Ohio. But a vote for Governor Kasich in future contests makes it extremely likely that Trumpism would prevail," he said.

Trump Refuses to be Daunted

Meanwhile, the GOP presidential nomination frontrunner was not fazed. On the contrary, Trump welcomes the recent development and says it can only be to his advantage.

"Failed presidential candidate Mitt Romney, the man who 'choked' and let us all down, is now endorsing Lyin' Ted Cruz. This is good for me!" Trump tweeted early Saturday, Mar. 19.

"Going to Salt Lake City, Utah, for a big rally. Lyin' Ted Cruz should not be allowed to win there - Mormons don't like LIARS! I beat Hillary," he also posted.
