Was it a snub?

Saturday at USD’s graduation ceremony (121st Spring Commencement Exercises), former Senator, and hot-in-the-news, George McGovern was on hand to receive an honorary doctorate. On the program it listed that President Abbott was to give McGovern the accolade, but he didn’t, Acting Provost and Vice President of Academic Affairs Matthew Moen did the honor.

Given the recent big news that McGovern switched his support from Clinton to Obama, did Abbott snub McGovern because he’s in Clinton’s camp?
