Texas senator Ted Cruz was booed off the stage at the Republican National Convention after refusing to endorse GOP nominee Donald Trump.

Cruz, who’s still holding a grudge against Trump for the nasty barbs they exchanged during the primary battle, urged voters to “vote your conscience” while failing to mention Trump at all.

“To those listening, please don’t stay home in November,” Cruz exhorted.

“If you love our country, and love your children as much as I know you do, vote your conscience, vote for candidates up and down the ticket whom you trust to defend our freedom and to be faithful to the Constitution.”

Ted ignored raucous chants from the convention floor, where disgusted delegates urged him to “Endorse Trump!”

In September 2015, the GOP asked all 17 of its presidential candidates to sign a loyalty pledge affirming they will endorse and support the eventual nominee.

Cruz, the author of A Time for Truth: Reigniting the Promise of America, signed the pledge, but failed to honor his promise.

Interestingly, Trump had dubbed Cruz “lyin’ Ted,” and it seems the senator is living up to his dubious moniker.

Cruz was widely slammed by Republicans, who called his speech self-serving. Ted reportedly wants to run for president in 2020, even if Trump is elected president.

But Cruz was also praised by some Republicans. Among them was former Ted Cruz spokeswoman Amanda Carpenter, who gushed over her former boss.

“This is the speech of Cruz’s life,” Carpenter tweeted. “Cruz stays true. This is a defining moment.”

In March 2016, Amanda Carpenter made headlines after the National Enquirer claimed she was of five mistresses Cruz had cheated on his wife Heidi with.

While a politician having extramarital affairs is hardly earth-shattering news, Cruz has vociferously touted his religious devotion and conservative family values.

The National Enquirer published a pixelated photo of Cruz’s alleged mistresses. One of them appeared to be Amanda Carpenter, a CNN contributor who despises Trump.

Cruz, Carpenter, and the other three alleged mistresses all denied the cheating reports.

The National Enquirer continues to stand by its story.

Ted Cruz, a Harvard-educated litigator who argued nine cases before the U.S. Supreme Court, has not threatened to sue the tabloid or even demanded a retraction.
