Texas blog Burnt Orange reports:

There is method to the Clinton campaign’s mad preemptive sword rattling over the Texas primary/caucus. They want to delay and disrupt the reporting of the delegate count. They hope that if they win the popular vote, they can avoid, at least for one news cycle, news reports that even if they do so they will very likely lose the delegate fight in Texas and fall further behind Obama in the national delegate contest.

This is not speculation. This has been the subject under discussion. While I have not been part of that discussion, plenty of sources last night and this morning confirmed this as the core of the dispute….

Throw the Texas delegate results in dispute, and win or lose the popular vote, they will have advanced their case that the contest remains close and should go all the way to the convention if necessary….

The Clinton campaign strategy is to justify taking the fight beyond Texas even if they fall further behind Obama in the national delegate count. To do that, they must cast doubt over the fate of the 67 delegates that will be chosen at the caucus level. Hence, their tough positioning in phone calls with Texas Democratic Party officials and others involved in the primary here.

The Texas rules have been in effect for decades. Bill Clinton ran twice under these rules. They are no surprise to anyone, and both campaigns know they have to play by the same rules. There is little point to raising concerns before the election — except one campaign finds itself running a very unique kind of effort. To remain viable, the results of the caucus in Texas must be thrown into doubt. Almost any legal challenge will do. The Clinton narrative can be maintained– but only if their falling further behind in delegates is not reported or is at the least cast into doubt for a news cycle, or two or three news cycles.
