One thing not enough people consider is the closer we move to a  strict limit on contributions the closer we get to a re-connection with single voter politics. The notion of a single vote being able to influence political decisions. Obviously our current system has created the opposite scenario which only continues to disenfranchise voters and erode voter turnout,  which few would argue is approaching disastrous levels. When less then 30% of eligible voters decide our elections we simply no longer have a representative government. Strict limits on contributions and single term limits are badly needed before we can begin to rebuild faith in our government at every level.
