If you would prefer a socialist party candidate the most logical choice is to pick whatever Democratic/Republican candidate is most willing to enact voting method reform, e.g. ranked choice voting.

Because voters are incentivized to pick one of two main parties in the current method, third parties are essentially guaranteed never to get off the ground.

Interesting. This kind of bill is for costs incurred as a result of the rally rather than for directly using the facilities, e.g. paying for an increased police presence to control protestors. Seems like candidates are not really obligated to pay for this.
