The midterm elections have been rough on Democrats, but they did well on one key issue they've been championing for months, a higher minimum wage.

Voters in Alaska, Arkansas, Nebraska and South Dakota -- all red-leaning states -- approved proposals to raise their state-level minimum wages over the next few years.

They join 12 other states and Washington D.C. for moving towards higher state minimums.

  • Alaska: From $7.75 per hour currently to $9.75 per hour by 2016.
  • Arkansas: The minimum wage will rise from the current amount of $6.25 per hour to $8.50 per hour by 2017.
  • Nebraska: From $7.25 currently to $9.00 by 2016
  • South Dakota: From $7.25 currently to $8.50 in 2015 and adjusted for inflation thereafter. 

Florida's state-level minimum wage was enacted in 2005, raising the federal minimum wage by $1.25 per hour. Since 2005, the state-level minimum wage has risen from $6.40 per hour to $7.93 per hour; a rate that is in place for 2015, but is adjusted for inflation.
