JEFFERSON CITY, Mo. – Emboldened by big majorities and eager to lure businesses, Republican legislators and governors across the Midwest and South are planning to pursue hundreds of millions of dollars of tax cuts in the new year.

Oh yeah, they might raise some taxes, too.

In many states, the exuberance to cut taxes during the 2013 legislative session suddenly has been chilled by worry about the potential consequences. Cautious state officials are now talking about the need for "thoughtfulness," warning that they'll "have to see how their numbers work out" and suggesting that tax cuts in one area may need to be offset with increases in another.
