(No longer a registered Republican, so I'm not voting in the primaries.)
He'll tell it like it is on many issues. That should keep other potential candidates focused on the issues US citizens outside of DC and the corporate world care about. I also believe that Trump would be the one to know how to get US citizens back in the workforce.
People forget. Ross Perot, with his charts and clear explanations of complicated issues, could've won the first time he ran. He should've chosen a viable and proven VP.
With a mad-as-*ell US population, I'm wondering if Trump/RandPaul just might win over voters.
