I had read that Sander's supporters were registering with the American Independent Party so they could be "independent" and vote for Bernie. Then they found out the AIP was a very conservative party, using scripture as part of their party plank. Now they find out they can't even vote for Bernie because they are registered with the wrong party.
And so they are suing.
Some airheaded actors (Kaley Cuoco was one) registered with AIP, not knowing it was the party George Wallace created to run for POTUS in 1968.
Epic Fail, to say the least. Not surprised they want a re-do.
