On the other hand, Chris Lavery, Clinton's California Political Director had this to say:

...the people running as Obama delegates (should) [sic] support Sen. Obama. We don't believe that anyone should try to beat the system.

The chair of Sacramento for Obama was concerned about a number of delegates that were not known to the Obama campaign and questioned their motives:

I don't know what their motivation is. I'd like to trust that it's pure. We just want to make sure we work as hard as we can to have rock-solid support for Obama.

David Karol, a political science professor at UC Berkley says that historically, for the most part, pledged delegates haven't changed sides except when migrating from a candidate who has withdrawn:

I think it is unlikely that we will see a significant amount of switching on the part of pledged delegates as long as both candidates remain active. In the recent past switching has not been very important and has chiefly taken the form of delegates moving from defunct campaigns to the camp of the prospective nominee.

California Democratic Party Spokesperson Bob Mulholland said that it's not that often that a candidate blocks someone from being a delegate unless they've donated to the other candidate and that this year's cuts are unprecedented.

On the other hand, according to Nathaniel Bach at Huffington Post, some die-hard Obama fans were also cut from the list (including him). He says the Obama campaign needs to right the wrong and reinstate the entire contingent of prospective delegates. He says that one Obama supporter who traveled to 10 states to volunteer for Obama was cut. At the least, he'd like an explanation from the Obama campaign of why he and other Obama supporters were cut.

Merriam-Webster's word of the day today is velleity. As in, perhaps the Obama campaign was concerned that some delegates commitment to Obama might be more of a velleity than an unyielding loyalty (Sorry, I saw the word of the day email and just had to throw it out there).

California Obama Spokesperson Don Morrison said the rolls were cut due to both allegiance questions and time constraints. According to the San Jose Mercury:

In some districts, more than 90 people had signed up to run for as few as three delegate positions. In the 17th District, which includes most of Santa Cruz County as well as Monterey and San Benito counties, 26 people had signed up for two posts.

90 people running for a 3-delegate spot is a bit over the top. Were they really going to let all those people get up and give a 1 minute speech? That would take up at least two hours, plus time to vote, and they'd still only have 3 down and a few hundred left to be selected. Obviously some people were cut because their allegiance was dubious, but others needed to be cut for the sake of practicality, which is no doubt going to leave some Obama supporters disappointed.

If anything, we should see this as a harbinger of good things for the Obama campaign. Hordes of people signing up to be Obama delegates in a state where he lost. This bodes well for November.
