This shows exactly what's wrong with our whole election process.  Lobbyists, PAC's, big-time donors, monied influence, huge cash amounts, etc.  Most incumbents and challengers have big money behind them.  No matter who wins, they are beholden to those entities.  No one in their right mind believes there is no influence on the elected by these who donate; in so many ways it smells of bribery and influence peddling--and it stinks.
