Biden, Clinton, Dodd, Edwards, Richardson and Obama have all signed the pledge not to campaign in states that violate the Democratic Party's nominating selection calendar. Early Friday, just Biden, Dodd, and Richardson had signed on. Then Edwards and Obama pledged to do the same, and then Clinton joined in.
Did the DNC inadvertently help the GOP in its general election efforts to hold Florida in '08 and pick off Michigan? So argues Human Events' J. Rubin.
Speaking of the calendar, the Los Angeles Times has a "state of the race" piece about the Dem primary efforts in California. Clinton is the political machine, and Obama is the grassroots. The Democratic machine is AWFULLY powerful in California.
