AP looks at the numbers and sees Obama will sew up the nomination within a couple weeks:
Barack Obama's wave of superdelegate endorsements puts him within reach of the Democratic presidential nomination by the end of the primary season on June 3 - even if he loses half of the remaining six contests.
The Illinois senator has picked up 26 superdelegates in the past week. At that pace, he will reach the number of delegates needed to clinch the nomination - 2,025 - in the next three weeks, when delegates from the remaining primaries are included.
Sen. Hillary Rodham Clinton's best chance to slow Obama is to move the goal posts. She will get that chance May 31 when the Democratic National Committee's rules panel considers proposals to seat the delegates that had been stripped from Florida and Michigan. Those two states violated national party rules by holding their primaries in January and lost their delegates.
Those goals posts aren't moving. But, there is continued movement towards Obama.
In fact, it's going from a wave to a cascade towards the inevitable nominee. Politicians want to get on the winning team. I mentioned one superdelegate endorsing Obama, (Rep. Joe Donnelly), in the open thread below. Jed reports on two pick ups last night, one in DC and one in Maryland. Interesting, the delegate from Maryland, Jack Johnson from Prince Georges County is a pledged delegate, not a super:
Unlike superdelegates, who are free to endorse either candidate, Johnson is one of 28 pledged delegates who have agreed to represent the 36 percent of Maryland Democrats who voted for Clinton on Feb. 12.
Some Clinton delegates were chosen by voters at the ballot. Others, such as Johnson, were selected in consultation with the Clinton campaign by the Maryland Democratic State Central Committee, party spokesman David Paulson said.
Now, keep in mind, it was Hillary Clinton herself who talked about how pledged delegates could switch under the DNC rules. So, delegates are starting to switch, but away from her.
