Speaking of Pew, their numbers support my claim.
Pew did poll the Senate and Governor's race. For the Senate, Cornyn won the Hispanic vote 48-47. For Governor, Abbott gained 44% to Abortion Barbie's 55%. The poll I saw had it slightly closer -- something like 47/52.
As you note, Pew didn't report on the Lt. Gov. race, but the other poll had Patrick leading Letitia van de Putte (a Hispanic) -- which, in view of the Cornyn and Abbott results, certainly seems plausible.
I'm surprised NEP polled in Texas in 2014. In 2012 they did no polling in Texas because all the state wide elections were runaways for the GOP.
The NEP/NBC poll shows Patrick 46% - Van De Putte 52%.

Scroll down on that same page, and they ask all Texas voters if “Ted Cruz would make a good president?”
No - 50% (!)
Yes - 35%
By the way, this is not the first time Latino Decisions has tangled with the National Election Pool on Hispanic voting.
In 2004, NEP claimed that, nationally, 44% of Hispanics voted for George Bush. You will see that 44% number referred to EVERYWHERE by the GOP Amnesty crowd.
Pew and Latino Decisions challenged NEP’s math. It took 6 years, but NEP finally revised Bush's share of the national Hispanic vote to 40%.
