As needs in transportation spending have gone up but funding, especially from federal and state sources, have not kept pace, many places are looking locally to tax measures and bonding to fill in the gap. And as roads and suburban areas become more crowded and transit planning demands more funding, many voters are saying yes and ballot initiatives are coming at a record pace.

Hopefully on related are a growing number of States, especially in the West (think what you want about that) with medical marijuana laws or initiatives on the ballot (or even regulated legalization in Alaska). Adding another vice to the tax line up could be a good source of revenue for states with funding issues (which would basically be all of them). Somebody has to pay for those unfunded mandates like No Child Left Behind.
