Its a fragmented party that merely belies the outdated 2 party system.
Trump appeals the same way all dictators appeal.
First he promises things he cant or wont keep, stuff like deporting US born children is probably a constitutional violation. I doubt his wall is feasible or even viable option.
He tells people that NAFTA costs US jobs and he does not provide tangible alternative to any thing he rails about.
Kasich can parrot what he did in Ohio, but he does not flaunt his failures, lie in your office that they were accomplishments.... Water, Steaks, Trump U etc those were blatant lies... although he must have bribed Chris Christie with quite a few steaks.

1. Trump is charismatic and dictators are charismatic. Therefore Trump must be a dictator.
2. Trump would win the most or second most seats in a parliamentary system too.
3. When had Trump ever said he would deport US citizens? I've seen it mentioned here a number of times (including the rabbi) without any backup.
4. A wall is both feasible and viable, and in case you didn't know, Cruz and Rubio also support the wall.
5. He's addressed NAFTA a number of times. He said he would negotiate a separate trade deal with each country.
6. Trump clearly said the water, steak, and magazine companies only catered to his own venues. They are not failed businesses just because Mitt can't find them in his local grocery.
