There should be a split between public and private sector unions. Is it finally coming to the surface?

Unions such as the International Longshore and Warehouse Union have recently left the public sector union dominated AFL-CIO.  Even the AFL-CIO is acknowledging that Obamacare is forcing employers to change full-time jobs to part-time ones.  Bigger government and higher taxes might help public sector unions, but it will help put private sector unions out of business.  From the WSJ:

"One of the tectonic shifts in politics right now is the separation between some fiscal conservative Democrats and public-sector unions," says Pete Peterson, executive director of the Davenport Institute at Pepperdine University. Mr. Peterson points to battles in California cities between Democratic mayors and public labor groups over government budgets and worker benefits. . . .
