1) They should have known about these rules LONG AGO.
2) If they had a problem with them, say, in August of 2007, it still may have been too late to change the process (with a Republican Gov and Legislature) and perhaps too late for a court challenge, but that would have been the time to do it, if not earlier.
3) The rules are unfair, but everyone is playing by the same rules. You essentially have two states voting in Texas: The Texas Primary and the Texas Caucus. This would be MUCH better messaging from the Clinton campaign-- then they could tout winning the Texas "primary" regardless of the delegate count. Instead they are nitpicking the rules.
You know what those superdelegates are thinking?
"Why the hell didn't you know about these rules a long time ago?!"
The operative term is "Clinton operatives discovered"--
It's a pretty late date to be figuring this out just now. There ARE Dems in Texas who are Clinton backers- and their campaign should have been in tune with the Texas rules MONTHS ago (as Obama's campaign was).
If this the team you REALLY want running the general election campaign for Dems?
