How does squandering $300K on amnesty ads benefit the SEIU’s due-paying members?

Via HuffPo:

The Service Employees International Union will begin to air $300,000 in ads nationwide on Wednesday to call for a pathway to citizenship for undocumented immigrants.

“Our immigration system is broken, and Congress has a chance to fix it the fair and accountable way, with back taxes paid, English learned and a real path to citizenship,” a voice says in the ad. “No half measures. Let’s fix it once and for all.”

“Tell Congress: Pass commonsense immigration reform with an earned path to citizenship,” the ad continues. “Because in America, we fix what’s broken.”

SEIU, like the AFL-CIO labor federation, argues any immigration reform must allow some of the estimated 11 million people living in the United States without authorization to gain green cards and eventual citizenship.
