I think this is an election unlike any other. Cruz is not connecting with the majority of Trump supporters with this kind of "attack". Only really conservative folks care.
I take Hannity's pov on this stuff. Donald Trump has been in the construction business his entire life--he's not a politician. But, he has had to deal with politicians to get his projects done.
He developed significant properties in New York and as a businessman has had to do his share of schmoozing and greasing of political palms, including senator Hillary Clinton's, even inviting her and Bill to his wedding.
That's what our wonderful political system has become and they all do it, including Mitt Romney, whose company, Bain Capital, gave millions in political contributions...to democrats.
Curious, I don't recall any hyperventilating threads here when Mitt Romney ran for president over his political contributions to the democrats.
