The slightest reasons really????
So you consider the flood of illegal immigrants the slightest reason?
The Global Climate lies the slightest reason?
Big government Republicans the slightest reason?
Then you clearly can not see the disaster it will create.
I don’t like it either, but it’s the nature of politics.
Being absent from the process, or throwing your support behind somebody who cannot win, gives the other side a clear path to do whatever they want.
Pick the best candidate and fight like hell for him, but don’t give the other side a clear path by being absent.
