This is complicated, so bear with me.   Delegates for each precinct are apportioned based on PRIOR voting history.   To be honest, I'm not sure if it's based on Governor's race two years prior, or President's race four years prior.  But either way, that's how it works.  For this discussion, I'll use 2004 results.

A precinct in Brentwood in mid-town Austin has 96 delegates to the County Convention.  This is because they voted heavily for Kerry in 2004.

 My new precinct in North Austin borders red-state territory, which is basically the rest of Texas.  It voted significantly for Bush in 2004.

Also, as Election Judge, I over heard at least half a dozen voters mumble to someone else that they were Republican's crossing the line to vote for [whisper], [whisper].   Later that night, a Williamson County Rep Candidate claimed that he lost his bid because 15-20% of Republican voters participated in the Dem primary rather then the Republican.

So...  Where I live, those crossover Rep's impact was reduced, because we have fewer delegates to the County convention.   Brentwood, where there are far fewer cross-over Republicans, has twice the number of delegates allocated to the County Convention. 

 As insane as this all sounds, it's possible that the caucus/convention portion of our process actually may have REDUCED the impact of cross-over Republicans.

Now there's been confusion as to who those Rep's voted for.   The racists wanted to vote for Obama, because they don't believe the country will vote for a black man (their words).   The politically active Rep's and those that listen to hate radio realize that the only way their weak nominee John McCain will be able to rally the troops, is to have Sen Clinton as the Dem nominee, which will be a big fat bulls-eye for lackluster Republicans to get up off of their couches and go vote against.

But, given the organized call by hate radio to cross-over and vote for Hillary, let's assume that the majority of those votes went for Sen Clinton.

With the cross-over votes, Sen Clinton won the popular vote by 3%'ish.   But did those cross-overs go to the precinct conventions?   Likely not, but if they did, the insane sounding apportionment system that grants delegates would have lessened their impact.

So - I know it all sounds mad, but let's not toss the baby out with the bath water just yet.   Let's give some time to analyze the data, and see if this complex system worked after all.

 AND... You may not have to worry about how the Texas system works for another 30 years.   Keep in mind that many of these rules have been around for a while.  It's only because of this extra-ordinary race that all of this has come to light.

In the future, we'll just be taken for granted, and all vote for the candidate that Iowa and New Hampshire pick.
