Voters in Arizona, Colorado, Washington and Maine are poised to approve an increased minimum wage, according to NBC News projections.

In Arizona, residents voted on Tuesday to pass Proposition 206, raising the hourly wage floor from $8.05 to $12 by 2020, with incremental increases along the way. The measure also includes some level of paid sick leave.

Similarly, Colorado voters supported an increase from $8.31 to $12 in 2020, starting with an initial raise in 2017.

The federal minimum wage remains $7.25, but voters are demanding more and taking it to the ballot box.

An initiative in Washington lifts the wage floor from $9.47 to $13.50 by 2020 and mandates that employers offer paid sick leave. In Maine, voters approved an increase to $12 by 2020 from $7.50 today, according to NBC News.
