NEW YORK (CNNMoney) — 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.

Based on the results tallied by 1:15 a.m. EST, voters in Arkansas, Nebraska and South Dakota — all red-leaning states — had approved proposals to raise their state-level minimum wages over the next few years.

Arkansas: The minimum wage will rise from $6.25 an hour now to $8.50 by 2017.

Nebraska: From $7.25 today to $9.00 by 2016.

South Dakota: From $7.25 currently to $8.50 next year; it will be adjusted for inflation thereafter.

They join 12 other states and Washington, D.C., all of which have moved in the past two years to raise their state minimums.

Alaska, too, had a ballot measure calling for a higher minimum wage, but votes there are still being tallied.

Voters in Illinois also approved a measure Tuesday night to raise that state’s minimum wage from $8.25 today to $10. But the vote was nonbinding, operating as more of an opinion poll, and the results won’t change Illinois law.

Meanwhile, the Democratic push in Congress to raise the federal minimum wage to $10.10 from $7.25 has gone nowhere.

At a more local level, voters in the California cities of San Francisco, Oakland and Eureka also were asked to weigh in on a higher minimum wage.

Votes there are still being tallied, but preliminary numbers suggest the measure was approved in San Francisco, where the minimum wage would be gradually raised to $15 by 2018, up from $10.74 currently.

San Francisco Mayor Edwin Lee declared victory on the issue, saying “San Francisco voters sent a message loudly and clearly to the nation that we can take on the growing gap between rich and poor, we can give a well-deserved raise to our lowest-wage workers, and we can do it in a way that protects jobs and small business.”

If the final tally does confirm majority approval of the wage hike in San Francisco, that city will be at the front of the pack with Seattle, which recently approved a $15 minimum by 2017.
