It should come as no surprise that prominent union leaders are among the first group President Barack Obama courts as he seeks support for overhauling immigration policy.

It was organized labor that helped ensure defeat of a bipartisan effort to reform the nation’s immigration laws five years ago.

At that time, the AFL-CIO and other prominent union groups came out against the initiative, fearing a proposal for a temporary guest worker program for seasonal workers would weaken union membership and bargaining clout.

That led to a handful of liberal-leaning Democrats to vote against the bill, including Sens. Sherrod Brown, Tom Harkin and Debbie Stabenow.
