Yeah totally. If Beto hadn't done that glory-seeking vanity campaign for President (i mean dude didn't even get elected to the Senate in 2018 and yet he wants a promotion into the White House) and gone bonkers, and if he'd just worked hard for the past few years building up the state party (and he could have did it too), he'd actually be in a really good position to run for Governor of Texas. And possibly win the damn thing... which would have in turn made him instant presidential material.
Sometimes pure naked ambition can backfire on you like a bitch.
If Beto hadn’t run for President in 2020, he would almost certainly have run for Senate that same year. A bid for Governor after two consecutive losses wouldn’t be on the cards.
