Last night's Republican National Convention was watched by millions, polarizing Republicans and Democrats and increasing awareness of where each party stands. Iowan Republican Senator Joni Ernst was chosen to give a speech based on the convention theme, "Make America Safe Again." She focused on national security while critiquing Democratic candidate Hillary Clinton.

Ernst claimed Clinton didn't stop terrorist groups like ISIS from expanding, and failed national security by using a private email server. She closed out by saying " With Hilary Clinton it's always about her, it should be about YOU." Sounds familiar...too late?
