A Quincy school teacher announced he will enter the Democratic primary for the upcoming special Illinois congressional election.

This will make the third time that Rob Mellon has run for congress. This time, he will run for the right to replace Aaron Schock in the U.S. House.

Mellon becomes the second Democrat to enter the race, following Springfield insurance executive Adam Lopez.

State Representative Darin LaHood is the only Republican so far to enter the race, although Quincy native Mike Flynn has a petition signing event Saturday so he can get in.

The deadline for submitting petition signatures is Monday. The primary is July 7th, with the special general election is September 10th.
