No they don't. The partys do. Mainly from Corp donations. Duke Energy mostly paid for the Democrat convention
The government(taxpayers) contributed about $130 million to both parties for their conventions. Congress needs to zero that out in the future!
here is a link that details how much both parties stole form the taxpayers!
The govn. pays for the convention center for both. They don’t pay for anything held outside the center.
I heard this discussed during the Democrat convention but it wasn’t said by a Democrat official. And there was a discussion of whether or not the federal govn. should continue paying for this.
