There's gonna be a lot of people looking for a new party if Trump is the future..
The people ARE looking for a 3rd Party, which is WHY they are turning to Donald Trump.
People believe America is great, and for 7 years they have had a Socialist who hates this nation so much that he promised to 'fundamentally change it' and has done his best to do so, who went on an apology tour as soon as he got into office. People want a proud American as President, who wants to make America great again, who wants to make this nation / our national security / Americans a higher priority that illegals, terrorists / refugees, etc...
They are tired of corruption, self/party-serving, elitist, non-representative Oligarchist wanna-be rulers who are more interested in protecting their power / positions / money, even to the point where they will roll over when they have the majority and / or to the point they will sabotage their own Presidential election candidacy. That's all Republicans have had for a long time now...all they have now.
People want a leader, a confident man of action who listens to the people and says what they want to hear - what they feel. that is Trump right now. Trump isn't a Republican, but he is THAT man right now... and people are flocking to him. The GOP, meanwhile, like lemmings heading over the cliff, are still refusing to listen to their base, still determined to pick their candidate - not the people, and ram it down their throats...and that boat is sinking.
We are also seeing many Democrats starting to embrace Trump, as well, rejecting the Washington Establishment, crooked career politician Hillary and the Socialist Bernie. Trump kinda spells doom for the GOP...and maybe will even hurt the Democrats, as neither party is listening or giving a very good choice / mix of candidates.
