President Trump rallied his supporters in Wilkes-Barre Township, Pennsylvania, Thursday night for the second of three "Make America Great Again" rallies in one week. The rally was ostensibly to champion GOP Rep. Lou Barletta, who is running against Democratic incumbent Sen. Bob Casey — but it encompassed many of the president's go-to topics. Mr. Trump called Barletta "dynamo." Barletta, for his part, praised Mr. Trump in a brief but energetic speech. The president dubbed Casey, "Sleeping Bob."
