Actually, it was a 13-way race.
The 2016 Texas Republican Primary ballot listed thirteen candidates:
Jeb Bush
Ben Carson
Chris Christie
Ted Cruz
Carly Fiorina
Lindsey Graham
Elizabeth Gray
Mike Huckabee
John R. Kasich
Rand Paul
Marco Rubio
Rick Santorum
Donald J. Trump
Every candidate on the ballot received more than 5,000 votes, except for Christie, Fiorina and Santorum, who each got more than 2,000 votes, and Graham who got just under 2,000 votes. Five candidates (Carson, Cruz, Kasich, Rubio and Trump) received more than 100,000 votes each. Cruz won 44% of the vote, Trump came in a distant second with under 27% of the vote, and the other 11 candidates split the remaining 30% of the vote.

If you just want to count the votes for Cruz, Kasich and Trump, then Cruz got 59% of the vote. Is Trump going to get 59% of the vote in a race with just Cruz, Kasich and Trump?
So far, Trump has never won a majority in any state. If Trump cannot win a clear majority in NY with only two other candidates on the ballot, then he can never win a majority anywhere.
Didn’t Cruz win the majority in Utah and Maine and maybe one more state?
Don’t forget to count those Elizabeth Gray votes. How could Cruz get 50% with that competition. LOL.
