First Lady Booed

The First lady Michelle Obama and Dr. Jill Biden, wife of the Vice President, traveled to Homestead, Florida in order to rally support for military families as well as simultaneously shout, “Gentlemen, start your engines!” They were noticeably booed.
I got to thinking, where would they have received a more inhospitable and rude welcome?
The church. Which, by the way, many of the NASCAR fans attend. Ignorance is bliss...
