Rubio didn't even endorse Romney.
His words are worth less than spit.
You're kidding, right? Look up the word, endorsement.
He's a US Senator from Florida, where the next presidential primary vote just happens to be scheduled. No, he didn't officially endorse Romney (in so many words), but he sure did go to bat for him, and even lied about his being a conservative, which he clearly is NOT.
That obviously doesn't disturb you, which says to me that you're supporting someone else in the race, at the very least. Worse, though, is the fact that you seem to be ok with Rubio giving Romney that undeserved praise.
There is NOTHING to praise Mitt Romney for.
