ORLANDO, Fla. -- Racial slurs targeting Barack Obama were discovered spray painted Saturday night on dozens of city vehicles in Orlando. The vandalism happened in a City of Orlando parking lot on the corner of South and Orange.

Phrases including "Oboma smoks crack" and other phrases with racial slurs were written in blue spraypaint on the white city cars and trucks. Other vehicles appeared to have had their gas tanks tampered with.

Along with the paint, hundreds of business cards were left on windshields. The cards contain criticism of Obama on one side and support for Hillary Clinton and her family on the other side. The same cards were left on Channel 9 vehicles in Daytona Beach several weeks ago.

The vandalism happened the same night the Obama campaign kicked off its Florida organization with parties across the state.

Local representatives with the Obama campaign told Channel 9 they weren't aware of any similar incidents.

Orlando police are investigating the incident.
