I would definitely not categorize Trump and Trump supporters’ savage and nonsensical attacks on Cruz as “very light”. We’re gonna have to agree to disagree.
Not "very light" in terms of intensity, "very light" in terms of quantity. There's just no comparison to the concerted demonization that is occurring with respect to Donald Trump, from the Left,GOPe,Establishment, and Cruz himself.
With or without Cruz's help, it's an all-out, desperate, slanted bid by the entrenched Establishment interests to subvert the will of conservative voters. It's incredible, it's diabolical, it's shameful and, given modern day networking/media capabilities, unprecedented.
If Ted Cruz ever ends achieves frontrunner status, or becomes the nominee (unlikely, due to shenanigans), he will become the focus of demonization by the Left, Mass Media, and probably even the GOPe, and will face much of the same.
Ted Cruz ain't seen nothin' yet...
