It would seem that the new GOP strategy when it comes to party corruption centers on issuing a swift public condemnation of the guilty (or perceived guilty) individual followed by a swift ouster of the embattled colleague. Of course, this was the way it played it in regards to the action taken against Senator Larry Craig and to a great extent this swift action was a preventive measure to avoid the 2006 calamity.
According to the Politico, while the furor and outrage over the Mark Foley incident definitely played a role in members of the conservative base sitting home, there were other corruption scandals that contributed to massive GOP losses. In Ohio, Rep. Bob Ney's felony conviction greatly damaged the party as did the Rep. Duke Cunningham corruption scandal and criminal conviction in California. And who could forget the ouster of Tom Delay?
For the GOP, it is a smart move to take a zero tolerance policy towards party corruption. Unless the GOP remains proactive in this area and establishes that such behavior will not be tolerated and must stop, the party will be perpetually labeled the party of corruption and will suffer greatly because of it. Or, more accurately, it will continue to suffer greatly.
