Bush,(aka the Chimp), may have seemed larger than life for eight years, but he left a surprisingly thin legacy. Take his legislative agenda. No Child Left Behind is now widely unpopular among both liberals and
conservatives—so unpopular that Congress has spent the past five years assiduously avoiding a vote to reauthorize it. His tax cuts expired in 2010 and now restoring them has made the economy fly, DJIA, A&P, Naz at all time highs. His own party wants to repeal key provisions of Sarbanes-Oxley. The Supreme Court has effectively gutted campaign finance reform, found DOMA unconstitutional and Obamacare Constitutional. On the foreign policy front, his wars are widely viewed as expensive failures. And he was never able to get so much as a vote on Social Security privatization or immigration reform.
That doesn't leave much. Pretty much all that's left is the PATRIOT Act and the Medicare prescription drug bill. That's not much for eight years.
Beyond that, neither party wants anything to do with him. It's not surprising that Democrats still think of him as the Frat Boy President, one of the worst of all time, but what is surprising is that Republicans largely agree. Many historians will stand in line at his grave waiting to leave a pee to his incompetence.
