Consider how the republicans wasted just about the entire 8 years of the G. W. Bush presidency.
They didn't do much and most of what they did do made things worse.
Didn't they ever consider what a bad president could do with the power vested in the Patriot Act?
Didn't they ever consider what democrats could do with the immigration issue when they failed to seal the borders and strengthen the E-Verify system and make it mandatory?
Everyone knew democrats wanted to pass a version of Hillary Care if they ever won the presidency again but republicans did nothing to remedy the healthcare problems that gave democrats open issues.
So many of the issues that have been nightmares for us in the Obama era could (and should) have been dealt with and removed as issues before anyone ever heard of Obama.
In fact, if republicans had taken care of business back then it is entirely possible that Obama, or any other democrat, would have ever been elected in 2008.
