Outlaw lobbying altogether. Overturn the disaster of Citizens United. I'd even go so far as to suggest jobs in governance be distanced from any profit motive whatsoever: term limits, minimum hourly wage for clocked time, divestiture or held trusts of assets while serving, and the same health insurance and retirement as constituents get. Basically they should be beholden to the same standards as the least among us. It should be a humble civic duty, not a lifelong power search and personal enrichment quest.
