Nader, The USSC and the hanging chad did not cost Al Gore the 2000 general election but the mere fact he lost his home state cost him that election.
Multiple causes can exist, you know.
Gore's margin of loss in Florida was far smaller than the number of Nader votes. Hence, it's delusional to claim that Nader didn't cost Gore the election.
So put the blame where it belongs and if someone can not win their home state during a Presidential Election they do not deserve to be President...
Interesting standard. You seem to be claiming that if Hillary loses Arkansas, as is likely to happen, she doesn't deserve to be president. That doesn't seem very sensible.
But again, the point. Those Nader voters in Florida share a part of the blame for killing several hundred thousand Iraqis, no matter what their good intentions were.
Trump has been very clear about wanting to break all treaties with Iran and start a war there. A moral person will work to prevent that. An immoral person will stand back and do nothing, and then protest that it wasn't their fault. Except it would be their fault, because they could have attempted to stop it, and chose not to.
