This year we took control and managed to nominate a person who is not afraid to act like a winner. A person willing to fight. Yes, Trump is not perfect, but he is so much better than Hillary, unless of course you don't want to rock the DC perks boat. Cruz could not fulfill this role because he is simply not likeable enough.
The right decision has been made. Time to unite and fight together.
We finally manage to poke the GOPe/RNC in the eye and now folks are upset because we used "the wrong finger".
Cruz could become more likable by not "lecturing" when he talks - obviously smart and has honed debating skills but does not connect personally. That shouldn't be a requirement for the Presidency, but alas, it's hard to get folks excited about you if they don't feel some sort of affinity with you.
Cruz is smart and should be able to take a lot of lessons learned and be a killer candidate down the road.
