Rush is trying to dishearten conservative Trump supporters.
Been doing that for a long, long time during this election cycle. First, he thought Rubio was the man. Then he hitched his wagon to Cruz. At that point, he started insulting Trump, and his supporters, at every turn. He's just keeping up the status quo!
Commenting to your comment. I seldom turn on Rush anymore. He's disgusted me to the point I cancelled my 24/7.(which I've mentioned on countless posts)
