They were handing out provisional ballots all over the country!
That's why the turn out was so "Low". They haven't counted the provisional ballots, which many people were forced to vote on!
We didn't have to give many provisional ballots at the precinct I worked. Our election judge strongly dissuaded voters from casting them, because they were not going to be counted if they were cast in the wrong precinct.
We had more voters show up who were registered at other precincts than actual voters in the precinct. The main reason for this was that it is used as an early voting location, so lots of people remember voting there. We had a 92 year old woman who showed up, and we concerned about her having to drive to the correct precinct location. After the election judge explained to her that her vote would not count if she cast a provisional ballot, she decided to go the the correct precinct to which we drew her a map.
It's really amazing how little planning ahead many voters do. Many didn't know where their voter registration card were and didn't know their precinct number. I used the speed dial on my cell phone to call the county courthouse numerous times to get information on lots of voters. By late afternoon the phone lines were jammed, so I told the election judge about the county and state websites where I could get this same information. She asked the organization hosting the voting precinct if they had a spare computer we could access for this purpose and they did. It was much faster to access directly than getting through the phone bank at the courthouse even on an old pentium machine running Windows 95.
