Taking as given that money will always find a way into politics, could we approach electoral fairness by, in essence, removing national platforms and centralized party power and, instead, having advocacy groups (polled/ voted on for the issues that matter most by represented region) up for election and then tying that to a representative - whose success - working without predefined yeas and nays - is based on negotiated progress on those observed issues?
Candidates must agree in writing to uphold the Party Platform. An independent group elected will audit the votes of elected officials. If they score less than 85%, they may not run for re-election, as agreed. If they score between 85-94% they will have to pass a Pre-primary vote of confidence to be eligible for the primary. Make the platform mean something. Hold official's accountable. Don't allow incumbents carte blanche to run & suck up all campaign funds just because they are incumbents.

Create an academy for training future civil servants, modeled on the military academies and much as Hamilton proposed 200 years ago. Apparently Hillary Clinton had the same idea in 2008. Graduates would eventually become the core leaders in government agencies, providing continuity between administrations. Today most senior civil servants learned on the job as they made their way through the ranks, have no formal training in management, and are often replaced by a new administration.
