I like this article which ends with
“Mitt should crawl back into his hole and not come out until next groundhog day.”

Romney, the guy would not go after Obama as badly as he is now going after Trump, is a piece of human debris.
It kind of seems to me Romney ordered Rubio-bot to take down Trump before Super Tuesday and Rubio-bot failed and now Romney decides “if you have to do a job right, do it yourself”.
