Because he won't be on the ballot?How can anyone guarantee 100% that Trump won't be elected when he leads in so many polls?
Because he will be in jail?
Because his false facade of strength and success will collapse when his NY businesses are seized?
Because his cognitive decline will get worse?
Because his health will fail him after a lifetime of eating unhealthy food?
Because his rhetoric will continue to escalate and finally reach the point where people conclude he has lost it?
Because people want their abortion rights back and blame Trump for taking them away?
Because people would like the election to be about more than Donald Trump's legal problems?
Because a third-party candidate emerges that disrupts the race such that Trump loses?
Because polls don't vote, people do?
