Because LOVE IS BLIND?
If you follow my posts you will discover that I have posted mostly positive stuff about many candidates. That proves I am not a robot for any candidate, and that I look at life positively and inclusively. Glass is half full, not half empty. On the other hand I have observed the most negative posts are from supporters of senator Cruz denigrating other republican candidates. You rarely see that from Walker supporters, Rubio supporters, or any other candidate supporters.
I think Cruz supporters are doing a great harm to their candidate. It is delusional to think that more people will flock to their candidate if they denigrate others. It is the worst strategy if you want to succeed in business, or in a corporation. Friends are harder to make, enemies are easier to make. If Cruz supporters are so negative about others, is senator Cruz built from the same cloth? Denigrating and excluding others? I don't think so. From what I have seen, senator Cruz is always graceful to other republicans. Policy differences for sure. But you do not see him calling others kooks or other graceless epithets.
I try to tell them that all the time. They are down right vicious in their attacks on Trump. If they do not like what Paul is saying wait till James Carville decides take up some of these issues.
