Excuse me!! Angela is a Mississippi, Black Republican lady who ran
for congress in Mississippi's 1st congressional district in 2010.
You’re correct, lots of black Republican women have run for Congress; in fact, quite s few have actually won the GOP nomination before (McGlowan couldn’t get that far), including one (Teresa Doggett) who came relatively close to winning. The author, who apparently isn’t very smart, must have meant that if (God willing, when) Mia Love is elected she’ll be the first black Republican woman in congressional history.
