Not voting at all is essentially a vote for Hillary. Call it a half vote.
The very least we should all be able to agree on, despite the invective and venom between the 2 camps, is that we will vote for eventual nominee in an effort to defeat Hillary. Whether that be Cruz or Trump. And I detest Trump, but if that is my option against the shrill bag of bones the Democrats are going to nominate then yes, I will vote Trump.
If we could all at least agree on that, then maybe there would be less suspicion and hostility between the 2 sides.
I think that most people secretly agree, but nobody wants to say so because they think it will weaken their side.
Frankly, having all of these Trump supporters threatening to bolt makes me even more convinced that I want to vote for Cruz. I suspect that their screaming like this is going to wind up turning a lot of people off in the coming primaries.
