It's because Trump talks tough. They think because Trump talks louder and less like a regular politician that he's believable.
Personally I could give two bleeps about how one talks. I care about action. Trump donated to a traitor in John Kerry. He donated to Hillary. Cruz has the record. While no bet is 100% safe, I have a good idea what to expect from Cruz.
Amen, brother.
I will vote for Trump if he is the nominee because he is likely to be better than Hillary, but I’m not excited about it.
