It seems more likely than not that they will rig the game one way or another to stop Trump and ignore why people are even voting for him, because it is really a vote against the establishment. This appears likely to explode in total chaos for 2018, and as we look into the 2017-2020 time period, it appears that they will destroy the public confidence in government on a wholesale basis.
As it now stands, they will most likely hand the nomination to Cruz one way or another. Trump’s only chance would be to run to the Libertarian Party since there would be no time left to get on all the ballots as an independent. Cruz would lose against Hillary and Hillary will destroy the economy with massive tax increases while protecting the banks. It appears we are indeed sowing the seed of our own destruction. The Republicans know Social Security goes negative in 2017, so they want to blame Hillary. Meanwhile, Trump shoots himself in the foot all the time and the media is in a full-blown assault against him. This is likely to undermine the entire confidence in government especially since Cruz came out and said he would not support Trump, only himself.
