That's a pretty serious accusation about Cruz. It would help me if you could provide exact quotes from Cruz not what someone else said he said.
Assuming you actually care, I will give you the benefit of the doubt and an example.
At the debate a week ago they talked about Scalia, and Trump offered two conservative judges for consideration. Nobody else on stage actually offered suggestions.
Two days later, Monday, Cruz was talking to voters, and he said that the only person Donald Trump ever suggested for the Supreme Court was his sister.
Cruz was standing right next to Trump at the debate, so it’s crystal clear that he was lying to voters.
There’s a laundry list of other lies that he’s either told himself or allowed his campaign/surrogates to tell.
He’s lost all credibility in my opinion. He should have fired his campaign manager after Iowa.
I’ll still vote for him if I must, but I’d rather Trump win.
