My personal opinion is the currently existing RINO party has been permanently shattered by Trump at this point. Whatever happens at the convention is almost beside the point now.
Trump will either be cheated out of the nomination by a combination of the corrupt RINO elite and the Cruz and Kasich trash, or he will win outright, or on a second ballot. The RINO party is DEAD ON ARRIVAL.
The brutal nature of the campaign, as well as the vicious nature of the attacks on Trump and his supporters by the RINO elite, the Cruz, Rubio and Kasich supporters means they can't stand each other. I don't know if Cruz or Kasich will go third party, or the RINO WHORES will dredge up some third party jackass to run against Trump.
Between Sanders and Trump the two party system has been revealed to be both a fraud and a farce. That knowledge isn't going away, since it means the underlying legitimacy for the entire American political system has been shattered. The consent of the governed is viewed with deep content by the party elite in both mainstream parties. The contempt shown working people, average people by the elite isn't even trying to be hidden.
I said way back at the beginning that Trump was going to permanently shatter the RINO WHORE party. He has done so. The idea the RINO WHORE party can be reborn is delusional. Whatever emerges out of the convention, Trump has redefined the idea of the Republican Party. He has added millions of new Republicans. They will not tolerate any continuation of the neo-con, warmongering, corporate free trade wing. The Bushes are GONE AND BURIED. Trump is the new Reagan. Trump will lead an expanded, populist Republican Party. Large numbers of the Cruz fools, the RINO elite, the neo con warmongers will either LEAVE THE NEW REPUBLICAN PARTY OR BE KICKED OUT OF IT.
The last time this happened was 1860 when the WHIG Party collapsed and was replaced by the original Republican Party under Lincoln.
We are going to have four political parties now.
We will have a hard left/socialist one.
We will have the remnants of the original corporate Democratic Party.
We will have the remnants of the RINO Whore Republican Party.
Finally, we will have the Trump, populist based new Republican Party.
It will be composed of the tens of millions of new voters he has brought in. It will be composed of those more populist based current Republicans, now trapped in the RINO whore Party.
The times they are a changing, indeed.
