Everything to some of you Trump supporters is a "lie". You yell "lie" more than Al Sharpton yells "racist".
And Romney's lame speech doesn't prove the GOPe fears one candidate over the other. Trump is the one leading right now, that's why the speech.
From day 1 Trump has taken 10x the heat of Cruz. Furthermore Cruz has stated that Romney made some good points. Cruz has also tightened his grip with the establishment as the nomination process has matured.
