Input: Poster: Another terrific event by the Tacoma-Pierce County Chamber this morning. The Economic Forecast was informative and gives me hope for a strengthening economy in 2013.  Responser: PLEASE look into cosponsoring the bill that would definately be a HUGE economic stimulus. It is the FairTax Bill and would do for our Republic what is already done for WA State "no income tax."
