“I am in this race because I don’t want to see us spend the next year re-fighting the Washington battles of the 1990s. I don’t want to pit Blue America against Red America; I want to lead a United States of America.” So declared Barack Obama in November 2007, making the case that Democrats should nominate him, rather than one of his rivals, because he could free the nation from the bitter partisanship of the past.

Some of us were skeptical. A couple of months after Mr. Obama gave that speech, I warned that his vision of a “different kind of politics” was a vain hope, that any Democrat who made it to the White House would face “an unending procession of wild charges and fake scandals, dutifully given credence by major media organizations that somehow can’t bring themselves to declare the accusations unequivocally false.”

So, how’s it going?

Sure enough, President Obama is now facing the same kind of opposition that President Bill Clinton had to deal with: an enraged right that denies the legitimacy of his presidency, that eagerly seizes on every wild rumor manufactured by the right-wing media complex.

This opposition cannot be appeased. Some pundits claim that Mr. Obama has polarized the country by following too liberal an agenda. But the truth is that the attacks on the president have no relationship to anything he is actually doing or proposing.
