Obama's perpetual campaign, OFA, has Aug 21st as their 'Day of Action' on gun control (note nothing on Jobs or the Economy) . In IL, they have 'rallies' planned in Springfield and Chicago.
Various anti-gun groups have tried this before. The turnouts have been.....less than stellar for them.
Basically they're using Obama's big money to push his political agenda in the face of lagging support. Take a look and see what's going on in your state.
