CLASSLESS SORE-LOSER TED CRUZ insulted Donald Trump and made a fool of himself at the Republican convention tonight…

…but leave it to Newt Gingrich to save the day and put Cruz in his place…in the gutter.

FYI: I refuse to post Cruz’s disgraceful, self-serving speech here, but he refused to even mention Donald Trump’s name and was booed by many in the crowd.
