Full disclosure: I am not a supporter of Donald Trump, nor am I a Republican. As a conservative, I routinely vote Republican. Of the four remaining candidates, (Trump. Cruz, Rubio, Kasich) Trump is the one I least want to see get the nomination.
Having said that, I have come to the conclusion that, while it is not inevitable, it appears Trump will at the very least go into the Republican convention in Cleveland with the most primary votes. This puts the RNC and the Republican establishment in a very difficult position. What they do may decide the future of the party itself.
We all know that the establishment is firmly against Trump. Their favored candidate is Rubio because they view him as the one who can best go up against Hillary Clinton in the general election. (They are probably right.) If Trump doesn't have enough delegates to clinch, there are all sorts of scenarios whereby someone else can snatch the nomination. They may even change the rules.
Either way, they are left with a very bad pair of choices: First, they can allow Trump to win the nomination fair and square and run in the general election. Even if he wins, the odds are great that he would be a disastrous and dangerous president. On the other hand, if the establishment steals the nomination from Trump, his followers will be so outraged they will probably stay home en masse on election day. If Trump feels cheated, he will no doubt run as an independent. Either way, that means a Democrat in the White House.
My feeling is that the Republican establishment, for better or worse, should avoid the smoke-filled room and let the winner prevail-whoever it is. They need to remember that is they who have helped create this monster in the first place. This is the inevitable result when the people feel that their leaders-the ones they have voted into office- have lied to them, cheated them, and failed to do what they said they would do. Here I am talking about people like John Boehner, Mitch McConnell, John McCain, Lindsey Graham, and many others. They told the Republican voters that they needed to give them a Republican House. They got it. They told the voters they needed a Republican Senate. They got it. Yet, nothing has changed. Harry Reid might just as well be the Senate minority leader, and Nancy Pelosi might just as well be the speaker of the House. Obama still gets everything he wants. When moderate methods don't work, the people turn to more radical solutions. (Europe is a prime example.)
So my advice for the Republicans is to listen to the voters. You stand to lose an entire generation of voters if you screw them once more. It is ultimately you who are responsible for this situation
