In 1994, 1996, and 1998 I worked on the campaign of a Republican congressional candidate. I put in a ton of hours dropping off literature, yard signs, doing phone banks, etc. I probably put in 20 hours or more a week in the active months of the campaign.
In 2000 I worked on the Bush campaign, doing phone banks and be a poll watcher. I did the same in 2002 for Scott McCallum's gubernatorial campaign.
From 2001 to 2006 I headed up the Wisconsin Concealed Carry Association and its political action committee. Besides helping on campaigns, I organized fund-raisers for the PAC. We raised $35,000 (not a lot, but a lot of work) in 2006, and lesser amounts in prior years.
Now I feel like I've done my time.
