If Trump could get his general election polling even against Hillary, the party would be rallying behind him. So you’re exactly wrong. They’re opposed to Trump because it looks like he’s the only one who DOESN’T have a chance of beating Hillary. You can feel however you feel, but the party overall is looking at polling to make up their mind. Trump needs to figure out how to turn that around if he wants to ensure he can make up any delegate gap at the convention.
We disagree on the basics. Trump is NOT a politician, he is a businessman, and a logician. He is looking at numbers, not delegates.
For him to win, the party needs to unite with him, and help and support him. Cruz and Kasich at this point are sacrificial lambs to Hildabeast. The longer they stay in the race, the better for the democrats. A separated house cannot stand, and the democrats are planning on it, counting on it. And hoping against hope that the republicans will not realize until its too late that they are destroying their only chance to win like play yard bullies. If they continue, they will all lose, and we will all Lose.
Each of them need to put on their big boy pants and unite to defeat the Democratic nominee. Only in Unity can we be victorious. Anything less is simply a waste of time and resources.
