Well, for multiple reasons, neither of those two candidates was someone I wanted to see in the general election. I looked seriously at both, paid little attention to the personal attacks, watched every debate, considered their experience, and their proposals including immigration, taxes, religious issues, foreign policy and domestic spending proposals. Neither Trump nor Cruz had serious realistic proposals on a number of issues. Hillary, Trump and Cruz had...and continue to have very low likeability ratings, each because of their own issues, Cruz included. If he's to be a viable candidate in 2020, he has a lot of growth to accomplish. He can do it though, and his future will depend on what he accomplishes, not what he stops.
You're telling me the "lyin' Ted' Trump twitter mantra, the Carson "stolen votes" smear, the birther bit, The whole someone in his church said he is the annointed of God thing, The Heidi is a Globalist banker tool who wrote the whole NAFTA thing, things, The five mistresses tabloid and allegedly two more (went away after one issue), the 'Heidi had a breakdown' bit, the 'stole' delegates in Colorado smear, the Dad killed JFK bit, etfrickingcetera had no effect? You just judged him on his SCOTUS briefs and time as an attorney and a Senator and the few campaign statements he could squeeze in edgewise?
Did you perchance notice the attack waves seemed timed for greatest proximity to a primary and/or caucus where that particular topic might have greatest effect?
I'm not impugning your ability to sift data, just saying it would be difficult to really sift through that intense dross and get to what Cruz actually said.
I had no qualms about his SCOTUS pick(s), given the opportunity.
The whole "unlikable" meme was based on him sticking to principle in the Senate, in opposition to the pandering to Obama of the GOPe, which as the crowing lie, he was supposedly a member in good standing. And, to be truthful, I would not be voting for Miss Popularity, but someone whose political stance agreed with my own and who had the grit to fight for that. Considering the people he was unpopular with (Boehner, et al), I find that to be a plus.
YMMV.
Maybe next time, but with the knack the GOP has for pulling defeat from the jaws of victory, I'm not so sure.
