I also think the campaigns need to be much shorter, without as much BS being tossed around. England allows what, 6 months to elect a PM??
If they need to spend $2 Billion for an election, it means they're not very good at getting the message out but the other issue concerns the lies- that needs to stop. They need to campaign on their own merits and an independent group should investigate any claims for accuracy WITHOUT bias and without weaponizing a government agency, regardless of the party/candidate's affiliation.
Maybe a boxing match with a referee, telling them to have a good, clean fight?
