On May 23, the New Hampshire Senate passed HB 588. It repeals the law that says candidates in a presidential primary must be registered members of the party that they are running in. The law has not been enforced in the past. New Hampshire election officials have no knowledge of how various presidential candidates living in other states are registered. The bill is now through the legislature.
Does that now mean that a candidate can run a fusion campaign in multiple primaries?
I guess so. Candidates pay $1,000 to run in a presidential primary, so if someone is willing to spend $2,000, I don’t see any barrier to their filing in both Dem and Rep primaries.
