Yep. I can tell you what happened in Texas anyway.
It’s called the Texas Two-Step. Voters vote in the primary and then after the polls close that night at 7:00 pm, they caucus with their party to commit delegates for presidential preference.
McCain had the nominatioy locked up by March 2008 when Texans voted, so Rush encouraged us to vote for Hillary against Obama.
When I voted, about one in four standing in line asked the poll workers if they could vote Democrat in the primary without affecting their Republican “registration.” I voted for Hillary and stayed to caucus with the Dems. It was chaos there were so many people.
The caucus workers were allowing people to enter the caucus who did not have their registration card stamped as having voted Democrat; telling caucus attendees not to fill out their presidential preference on sign-in sheets and then writing in Obama for them when they turned away; sending home those who were there to caucus for Hillary by telling them that their presidential preference had been counted by registering such on the sign-in sheets. All of that resulted in Obama having a far larger presidential preference count than Hillary and in his attendees staying to caucus and most of Hillary’s leaving. Delegate count is determined by the presidential preference on the sign-in sheets. So while Hillary won the actual primary, Obama stole the delegates by fraud.
Long story short, I was one of the few people there for Hillary who stayed until it was time to elect delegates. I was elected as a delegate because I was present. There weren’t enough of us to fill out a complete slate of delegates and alternates. I went on to caucus for Hillary at the Senatorial District caucus and witness even more blatant corruption and fraud. I filed an affidavit with the Clinton campaign twice - once for the precinct caucus fraud and then for the district.
So, in Texas anyway, Operation Chaos didn’t matter because Republicans didn’t know they were supposed to caucus after the primary and those who did were sent home early thinking their presidential preference had been counted.
