When America’s Millennials figure out how to register to vote, Sanders would probably crush any of his opponents on election day. There’s a reason the Sanders campaign has spent so much of its time trying to teach its idiot voting base how to cast a vote, because the socialist virus has almost entirely consumed the younger generations (and controls a large percentage of the older generations as well).
It's always unwise to underestimate your opponent. Those millenials who can't figure out how to register have propelled the old commie to victory after victory.
