All of them except for Trump.
Trump is the only one that is different from the Experienced Politicians, and competent enough compared to the few other inexperienced politicians to make it work.
Most of the rest are funded by money that comes with a commitment to pay it back, while Trump is using his own money.
He doesn't pander to the media or the party, and both of these have been the reason why the US is in a decline. The party should represent the people and unfortunately the party has controlled the people.
It is both parties with their divergent goals that has stalemated congress and the country. The party needs to get back to implementing the wishes of the voters, and not their third party investors.
I would gamble on Trump, and I don't think at worst would be any different than the rest of the herd. But, at best, I think it would be a win.
I can't say that about any of the other candidates.
