Voters take to the polls in the primary election at West University Elementary on Tuesday, March 6, 2018, in Houston.
Any Democrat hoping to win statewide in Texas and break a 24-year losing streak for the state party will have to draw lots of Latino voters to the polls.
As for his own use of Ted rather than Rafael, Mr. Cruz said, "You're absolutely right".
"I dont think it's about wooing Latinos", she said. But Cruz still has more money overall, with a campaign war chest worth $7.3 million compared to O'Rourke's $4.6 million. "It's about getting under Beto's skin".
CNN's Chris Cuomo and Cruz got into it on this subject this morning, with Cuomo suggesting the senator was something of a hypocrite, given his active dislike of the nickname bestowed upon him by Trump during the 2016 primary election, which was "Lyin' Ted".
The ad says O'Rourke "wants to take our guns" and calls him "liberal Robert", referring to his given first name.
Cruz agreed, saying he was named after his father, also Rafael Cruz, a Cuban immigrant.
For his part, O'Rourke tells CNN that he's been called "Beto" since day one, and he has the pictures of his custom-stitched baby sweaters to prove it. "We can get into name calling or talk about why the other person's such an bad guy, or we can focus on the big things we want to do for the future of our country". "Last night's results, in my opinion, validated all of that".
