I don't support any candidate yet. But Trump supporters accused me of supporting Jeb (who I was against long before it was popular), Cruz, and, yes, Walker. (In fact a Trump supporter just last week said I was a huge Walker supporter, which I never was.)
Trump supporters were attacking everyone in site viciously for months before their was any pushback. Cruz supporters were either kind of liking Trump or they were to scared.
So if you complain about Cruz supporters, maybe you should be looking at trump supporters for creating it. Trump supporters had carte blanche to attack everyone who dared to say anything about Trump, before any but a few (yours truly) opposed them.
Well, you weren't around the first half of the year as a Walker supporter, so your ignorance can be forgiven.
Cruzers have been mean spirited, and very personal, for over a year, it's only the target which has changed.
Ironically, Walkers ethanol position was a particularly vicious angle of attack by the Cruzers.
Walker called for a gradual phase-out of the Renewable Fuel Standards.
