Please encourage your friends and neighbors to vote in the primary elections this year. I think this will help build the habit of voting, and make it easier to turn out the vote in November. The official date is May 21, but early voting begins tomorrow, April 29. This primary is for all offices except the the Presidency, which had its primary back in March. I found a general summary of state elections at Atlanta News First, but most of these are local elections so your best bet for information will be from local sources.
Other voter guide is at the AJC. I did not see anything from public radio stations yet.
As always, the Georgia voter site can show your registration information and sample ballots.
