.....”not one of them has offered any specific evidence to support the claim.”.....
Sure they have...but they really don’t need to because Trump himself has admitted so. Any search into his history of these past 40 years provides the evidence....but only if you’re looking for the truth...otherwise your own eyes will blind you as they have thus far.
In other words, you have no evidence to present, either, or you would have presented it.
Trump has a long history of living and practicing a conservative lifestyle--or do you think some other capitalist genius is behind his empire? Nevermind, don't answer that--I don't want to hear a bunch of crazy conspiracy theories.
Just remember, we are not talking about some unknown person who suddenly stepped out of the shadows, about whom no one knows anything--we're talking about someone whose life has been public for decades. So the burden really is on those who claim he is liberal to prove it, since the public record shows otherwise.
