By Melissa Mackenzie, American Spectator - If Donald Trump’s good humor infects even the most sober of politicians, his ebullience positively electrifies crowds. Tonight, Houston is electrified. Jolted, energized and best of all, enjoying itself on the way into one of the tightest midterm elections ever. Win or lose, the Cruz Crew and the Trump acolytes are have a grand old time... Who doesn’t want to be part of the party? It’s fun. It’s infectious. After eight dour years of being told to accept the inevitable, Trump’s entrée into the political sphere is like the dawning of the sun.
