The Think Long Committee is not pursuing its tax overhaul plan this year, which will help narrow the number of competing tax proposals on the fall ballot. Gov. Brown has his own plan in the works, and there's been concern that too many similar measures could mean that everything gets defeated. Think Long will try again in 2014. From its statement (via Capitol Alert):
We recognize the practical constraints of the 2012 election calendar - and have come to the conclusion that it will take more time to perfect these proposals, eliminate unintended consequences and provide every stakeholder and everyday Californians a meaningful voice in that process."
