Former Gov. Jeb Bush, Florida

Who:
Bush is the former governor of Florida and is the brother of former President George W. Bush and son of former President George H.W. Bush. Despite his insistence against it, his name was floated as a possible presidential candidate this election year and as a possible running mate for Mitt Romney. Although he endorsed Romney, he differs from the candidate and the Republican Party sharply on the issue of immigration, and encourages the Republican Party to adopt a softer tone and move away from backing Arizona's immigration law.

Why:
Bush is popular in the state of Florida, popular among Republican Latinos and has national name recognition. He also appeals to the more moderate component of the Republican Party.

Role:
Bush has been given a key speaking slot on Thursday evening at 8 p.m. ET, the night Romney delivers his acceptance speech.  He was originally scheduled for Monday, before convention organizers canceled the first night due to Tropical Storm Isaac.
