text:  If Trump is the founder of the GOP's current America First agenda that attacks Democrats in the federal government, then Vance has positioned himself as the heir apparent to make America great again in the future. Though Vance once opposed Trump and called him, quote, America's Hitler, he's now one of Trump's most vocal supporters in Congress. Vance's selection as Trump's VP comes as the Republican Party leans into the former president's MAGA messaging that has fired up the party's base and could alienate a broader audience needed to win in November.
