In the post-recession era, "debt" is a four-letter word. State debt levels as a whole have been stagnant in recent years and, in 2014, actually recorded the first decline in the 28 years Moody's Investors Service has been tracking them.

It's in this climate that voters in Arkansas and California have cleared the way for more spending on mega projects that could be economic development boons in those states.

In Arkansas, voters overwhelmingly passed a ballot initiative that eliminates the state's current 5 percent cap on debt related to economic development projects. Proponents of Arkansas’ Issue 3, who included Gov. Asa Hutchinson, want the cap lifted so the state can be more competitive in attracting new corporations by helping fund mega projects. Voters easily approved the measure, 65-35.

In California, which has one of the highest taxpayer debt burdens in the country, the results were much closer. Voters narrowly rejected a proposal, 51-49, that could have derailed two of Gov. Jerry Brown's legacy projects. Prop. 53 would have limited the state's ability to issue debt for major projects by requiring voter approval to issue more than $2 billion in revenue bonds.
