An NBC News/Marist Univ. poll (PDF) shows U.S. Sen. Ted Cruz (R) leading U.S. Rep. Beto O’Rourke (D-El Paso), 49%-45%, among “registered voters” with just 6% undecided. The same poll shows Gov. Greg Abbott (R) with a 56%-37% lead over former Dallas Co. Sheriff Lupe Valdez (D).

The poll indicates a greater split among Republican candidates at the top of the ballot than what occurred in recent election cycles, but it probably less a function of conscious ticket-splitting and more a function of the candidates’ relative favorability.
