The most e-mailed column to me this evening is this from Morris:

In the days before Iowa and leading up to New Hampshire, Hillary was the prime topic of political discussion.
She took shots for misusing Bill’s record and trying to adopt it as her own, for minimizing King’s contribution to civil rights, for crying, for attacking her opponents, and for changing her campaign style to become more likeable.
Now, she rarely gets hit anymore. They’re hitting Bill instead.
Like a red cape, he is attracting the attention of the bull so his wife the matador escapes unharmed.
The other method behind his madness is that Bill wants to suck up all the oxygen in the room and dominate the coverage of the Democratic contest. By doing so, he cuts Obama out of the news, pushes him off the front page, and usurps the headlines.
Of course, he also crowds out Hillary, but that’s OK, given her large leads in the national polls and in all the big states whose primaries are coming up.
If there were a newspaper and television blackout, Hillary would cruise to an easy win, so Bill, by injecting himself into the coverage and hogging it, is accomplishing the same goal.
His tactics now are reminiscent of those he used to black out John Kerry during the lead-up to the 2004 Democratic National Convention.
By scheduling book signings and speeches in Boston, he effectively took the coverage away from the prospective Democratic nominee, a man who would have eclipsed Hillary’s presidential ambitions had he won the election.
Ultimately, the Clintons are playing a game of jujitsu with Obama, using his own strength against him.
By challenging Obama for the black vote – by promising to go door to door in South Carolina in minority neighborhoods, for example – Bill is highlighting the question: Will Obama carry the black vote? Of course, he will. He leads, 4 to 1, among African-Americans now.
But by making that the central question, Obama’s South Carolina victory will be hailed as proof that he won the African-American vote. Such block voting will trigger the white backlash Sen. Clinton needs to win.
Once whites see blacks voting en masse for a black man, they will figure that it is a racial game and line up for Hillary. Already, she carries white voters by 2 to 1.
The Clintons can well afford to lose South Carolina as long as the election is not seen as a bellwether of how the South will vote but as an indication of how African-Americans will go. It’s a small price to pay for the racial polarization they need to win.
