According to a story in Newsweek (via the Raw Story), George W. Bush's approval rating has slipped to an all-time low of 28%. That means roughly three out of every four Americans think Bush is doing a job they don't approve of. In other words, he's doing a bad job.
Like, criminally bad.
To put this in perspective, let's look at Richard Nixon's approval ratings over the 6-1/2 years of his presidency - via Drew Thaler's Recording Artist blog:
Nixon, who was a shrewd career politician and feared by most everyone, suffered a spell of dismal approval ratings in the mid-to-upper 20's during the infamous "summer of Watergate".
That was the three months of almost daily televised Watergate hearings that ended with the House passing all three articles of impeachment and Nixon resigning before his Senate trial could begin.
George Bush has attained these low ratings almost without even trying. Much like Nixon, he's involved in a war that seemingly has no purpose or direction. God only knows what Bush's "approval" rating would be had he gone through what Nixon experienced in those seemingly endless lazy summer days in 1974.
I think we'd have to invent a whole new branch of mathematics to describe his awfulness.
