Since I never voted for any Bush, your straw man does not apply. I'm not advocating being a Republican. I'm advocating being independent and making strategic decisions about candidates based upon core principles - rather than being a jersey-wearing die-hard fan of a political party.
That said, I do think that having a Republican administration take the blame for the current scandals (IRS, NSA, AP, Benghazi) would have been a good thing.
If we extrapolate the level of anal probing that went on as a result of the Valerie Plame outing to the above scandals, the media wouldn't let any of them go until something more meaningful happened in congress, in the courts, or in voting booths.
As it is, these scandals are all disappearing from the MSM's coverage. Maybe they can do another multi-month coverage of George Zimmerman-like trials to take our minds off of important things.
