In the last month, the Employee Rights Act (ERA) has gained 40 new co-sponsors in Congress. They include Sens. Tom Cotton (R-AR), Lindsey Graham (R-SC), and Marco Rubio (R-FL), three of the most recognizable Republicans on Capitol Hill. Graham and Rubio, who are presidential candidates in 2016, have both openly endorsed the bill on the campaign trail. And the pro-employee contingent is especially strong in the House of Representatives: 34 members have become co-sponsors since November, bringing the total to 72 overall.

It’s easy to understand the bill’s popularity: 80 percent of Americans support the ERA’s key employee-focused provisions, including an overwhelming majority of union members. And their appeal traverses party lines: 81 percent of Democrats surveyed support secret ballot elections in the workplace. Even more believe in secret-ballot strike votes. The federal criminalization of union violence registers above 90 percent among self-identified Democrats and Republicans.

Heading into the 2016 election, our political leaders are joining the masses.
