Florida voters have been receiving postcards that promote the Democratic Party and vote-by-mail balloting.
The cards have created confusion and complaints as they arrive at the homes of voters who are not registered Democrats, according to the Clay County elections office.
Although the postcards include the website and phone number of the elections office, they are coming from a third party, apparently a group called Postcards to Voters.
Postcards to Voters is a group of more than 75,000 volunteers who send handwritten reminders to voters in key races coast to coast, according to the group's website.
"While these postcards may be unwelcome, we stress the fact they are from a third party and not from our office," the Clay County elections office said.
Elections officials remind Clay County voters they can review their registration information and make changes at clayelections.gov.
