Paul Krugman's Sunday column  in the New York Times lays out what we're in store for if the Right can capture control of at least one chamber of Congress this fall:
The last time a Democrat sat in the White House, he faced a nonstop witch hunt by his political opponents. Prominent figures on the right accused Bill and Hillary Clinton of everything from drug smuggling to murder. And once Republicans took control of Congress, they subjected the Clinton administration to unrelenting harassment -- at one point taking 140 hours of sworn testimony over accusations that the White House had misused its Christmas card list.
Now it's happening again -- except that this time it's even worse. Let's turn the floor over to Rush Limbaugh: "Imam Hussein Obama," he recently declared, is "probably the best anti-American president we've ever had."
The piece in its entirety  is worth a read.
