Even his own party never votes for his stuff because his ideas are always terrible. They are always emotional, but he never thinks them through. I don't think he's able to think them through.
I'll give you an example from a different person: There's someone on Twitter who wants a 0.1% tax on stock transactions, and then he calculates that this little change will fund everything we could possibly want. He utterly ignores that if you put this tax people will change their behavior! There will be fewer transactions, and this tax will fund nothing at all.
Sanders is the same way: He makes an idea, and completely ignores how people will respond to it.
Sanders has a 0% chance of winning.
