In Arizona Republican Congressman Jeff Flake was robocalling democrats with incorrect information about the location of their polling location. His office claimed that few people called into their office to question the calls, and the calls only happened to republican households. However the Democratic homes in question said that there were no republicans in their households.
Double check your polling location with official documentation from your election office. If you are unsure call your county election office to find out where you should vote. Do not go by robocalls that ask you to vote for a specific candidate.
