That may be a nice Googlebomb, but Obama has also been Yahoobombed, with less friendly results.
Search Engineland reports that, "Do a search on Yahoo right now for miserable failure, and you'll find President Barack Obama's page ranking either in the top spot or the second spot. Given a redirect that Obama's web team has put into place, he should solidify into that number one spot over time. Eventually, Microsoft's Live Search should reflect that, as well. And over at Google, Obama will likely gain a top page listing for a search on failure."
I've performed the search multiple times through various different search engines. Search Engineland is right. A Yahoo search for "miserable failure" surely points to Obama. Performing the same search on Google right now leads to a bunch of results about Bush, Obama and Googlebombs. That search performed via Microsoft's Live Search still points to Bush at the moment, as well as articles abnout Googlebombs.
