TRUMP is more popular than the polls claim because people are keeping quiet but will pull the lever for TRUMP for sure.
There is definitely some inverse Bradley effect going on around Trump.... While Trump may not be everyone’s first choice, more folks are more than willing to vote for him, over Hillary, but its a very politically incorrect stand to advocate in many situations, so folks just quietly shut up, or say something else when asked about it.
I’ve had more than a few conversations where people have publicly mocked Trump in a group or work setting, only to admit privately, they will vote fro him without hesitation if he’s the nominee.
Nah, most Trump supporters aren't ashamed to support him. If the polls are underestimating his support (they probably are) it's because they're cooking the results by manipulating the weighting of the various demographics.
