Madison, Wisc.- Election official training classes were scheduled for Sunday and Monday, but due to President Obama's final rally in the state's capital Monday, the sessions have been cancelled.

The Government Accountability Board is now offering the classes in an online webinar. If the election officials don't watch the webinar, there is a real concern there will be many untrained officials in Tuesday's poling places, throwing election integrity in doubt.

This past June, during the recall election of Governor Scott Walker, Breitbart News uncovered many election irregularities, including many discrepancies between what poll watchers and official election judges believed to be the proper rules for poling places.
