Nope! Unless you accidentally put in so many numerical digits that the field would not be able to take it. And as far as I could see, no "double check" on the numbers. The numbers immediately posted up on the website and that was the end of that.
Something needs to be done about that. There has to be a way to audit the electronic records. At this point it’s basically a race to see who is willing to enter the most fraudulent votes. What shows up in the results could have absolutely nothing to do with what lever any of us pushes.
Before we get all paranoid over this, election numbers reported on board of elections website pretty much universally carry the disclaimer that they're unofficial, because they are.
The website is just a quick reporting tool to give the results of the election, but the official count of ballots is usually completed later and the official results are eventually posted. If there is a significant discrepancy, heads will turn, but that type of thing usually winds up being a data entry error (see the Wisconsin recall elections for a recent example).
