When it comes to campaign contributions or support, it would make sense to prohibit all cash contribution from anyone who is not a resident in the candidate's district or state. It make sense for the citizens of a nation not to allow foreign contributions to national elections and it makes equal sense for the voters of a state or of a district not to allow outsiders to bribe or impose their candidate or buy themselves one. The same restrictions should apply to the 'parties'. Since the elections are about citizens electing their representatives not parties imposing their agenda and party discipline, political parties should NEVER be allowed to contribute in any way to anyone's campaign.
