Not buying it, bob, Trump is the nominee largely because he has stood with the citizens and the rule of law.
Yeb!, Rubio and the other open borders candidates went nowhere.
McCain won against Hayworth because he had millions od dollars to carpetbomb Hayworth with negative ads, most of which were lies.
Mormons may want open borders, but the rest of America does not.
Trump is the nominee because he had the 40% of the voters that agrees with him on immigration. Plus he was more n anti=Washington than even Cruz. Plus Cruz, Rubio, Carson (the only 3 who were serious challengers to Trump) all ran flawed campaigns.
Trump and his supporters need to convince the undecided, who will be convinced on
1) anti crooked Hillary.
2) Small government. Hillary is big REMOTE government.
3) most important, friendliness, likeability. Insult the opposition candidate. But don’t insult the undecided voter.
