Infrastructure bond issues have roared back onto statewide ballots in this year's presidential election, with more than $4 billion dollars' worth tallied in nine states, up from $1.9 billion in five states two years ago, says the National Conference of State Legislatures, or NCSL.

In addition, there are finance measures on municipal or regional ballots, particularly large ones in Texas, and initiatives that could affect how industry firms do business in some states.
