You are insane if you think Palin will support Trump. And you are insane if you think she would ever be a VP candidate again. That is a ridiculous premise.
Making such definite statements about what politicians (any politician) will or won't do is very risky business.
The way it works, is that instead of just saying someone is insane for ther opinion,,, you explain the fallacy in their thinking.
For example,, i might point out that the veep is traditionally the attack dog. And that the veep is designed to appeal to a different block of voters,, say New York and the suit types,,, as opposed to Alaska and the Blue collar flyover.
You don’t pick a clone sport. Might not be him, but it might not be someone you’d expect.
Time for you to grow up.
