I think it'd be straight comedy if this joke ticket decided the election one way or the other!
Can someone put your name on the ballot against your consent?
As the article suggests, they can petition to put your name on the ballot, and it will then be on the ballot unless you take the initiative to ask for it to be removed. But it sounds like Bloomberg may not bother to ask them to remove it, which means that yes, he'd be on the ballot.
I think there is a rule about being registered with the FEC in order to make it onto the ballot, but I'll have to go look that up.
