You are right. Perry did the most vicious verbal attack on Trump, unprovoked. This is from a politician who received used to beg Trump for campaign donations in the past. He was obviously commanded by the GOPe to take Trump out.
“Perry did the most vicious verbal attack on Trump, unprovoked.”
Yes. Incessantly. He went on and on about Trump being a “cancer”.
A serious candidate does not make his campaign about over the top attacks on another candidate.
