The public line outside of the Supreme Court on Monday snaked around the corner. An old-fashioned demonstration with music, bull horns and placards played out on the sidewalk below the plaza. Had the culture wars returned to the high court? No, there were no abortion, religion or race arguments on tap. It was a high stakes, union fee challenge in the morning. Tuesday’s Microsoft challenge is unlikely to draw that type of a crowd but it is a huge case. We take a peek at the arguments that the justices will hear. Oh, and guess what gets under the skin of the chief justice of the United States? We have the answer.
