The Tavis Smiley Primary

Ben beat me to the punch in noting that Hillary Clinton's campaign announced today an endorsment from former Mayor David Dinkins, wihch was made public back on New York 1 back on May 4.

Yes, rolling out all the endorsements is a complicated science. But the timing of this announcement may have something to do with the black journalists who will question the Democratic presidential candidates at tonight's debate at Howard University in Washington.

Speaking of which, Steve Kornacki has a column previewing the debate, focusing on the governor who could be the next big Democratic thing. He'll also be back sometime this evening or early tomorrow with his thoughts, and stay tuned to this space for further analysis and reaction throughout the day.
