Union approval very partisan

Every year, just before labor day, Gallup polls the American public's attitude toward labor unions. 2010 post here. This year a few more Americans view unions in a slightly more favorable light (52%), up from a 2009 low of 48%. But the real story is the whopping 52 point differential between Democrats (78% favorable) and Republicans (26% favorable). Last year Republicans had a 34% favorable view.
