ALBANY, N.Y. (AP) — Minimum-wage increase proposals are getting the maximum push from Democrats in statehouses in more than half of U.S. states, highlighting the politically potent income inequality issue this year.

Lawmakers in at least 30 states are sponsoring or are expected to introduce wage hike measures, according to a national review by The Associated Press. They hope to notch state-level victories as President Barack Obama and congressional Democrats remain stymied in attempts to raise the federal minimum wage above $7.25 an hour. The president is expected to mention the minimum wage in his State of the Union address Tuesday.
