I think Ted Bush is screwing himself for 2018 by doing what he is doing.
I think so, too. After watching Cruz for a few weeks, I decided that the USA just wasn't ready for him to be president for a variety of reasons. Also thought his ticket to higher office should be as Trump's VP so the nation could become accustomed to him as VP and able to support for president later.
He might have blown his political future with so many peculiar and mostly self-serving statements and moves in recent months.
We can hope
I don’t see him being unchallenged in 2018, if he even runs. 44% is not a impressive sign of support in the Texas Republican primary. He might go into his father’s business, so to speak.
