Ok, ok - I've got it!
Trump is getting close to having enough delegates to win the nomination. But the GOP by and large doen't like him. So they will be in a bit of of pickle - follow the will of the Republican majority or do what they please. Nominating someone else will not be well received by many - as it's a bit of a cheat. So, what will they do?????
Shut down the election! They will nominate NO ONE. And block the election going forward.
Remember these are the famous Republicant's;
Their version of health care reform is to do nothing.
And if elected they will undo everything they can so that nothing was done - about most anything.
New supreme court justice? - NO ONE! They take the action of doing nothing.
And they will steadfastly work overtime (with pay) to do NOTHING.
But this is not being fair - they do work hard to shut down the guvmut.
And that IS something I reckon......
