The current AFFT Co-Sponsor list (not updated for 111 Congress yet) shows 72 House Members plus John Linder (Sponsor) and 4 in the Senate plus Saxby Chambliss (Sponsor). Your numbers are higher than their totals.
The 110 Congress first session started out with 24 Co-Sponsors when it was introduced. This session has 34 Co-Sponsors with one new one on 1/8/09.
It's a new year, a new President, a new congress and a new outlook. I suggest we take an escalating approach to reaching 100 co-sponsors before year's end. Maybe we should start with emails to our reps, then escalate to snail mail letters, then to phone calls, then... I dunno maybe find their cars and cover 'em in FairTax stickers... well, maybe not, but you get the idea.
