WASHINGTON (Reuters) - When Donald Trump met with advisers about his plans for campaign appearances in the final weeks for the battle for control of the U.S. Congress, the president surprised them by insisting they add more events to an already-crowded schedule.
His strategy for the final stretch has been simple: Drive Republican turnout by focusing on an issue that appeals to his core supporters - illegal immigration - using as a foil a large group of Central American migrants making their way slowly through Mexico toward the U.S. border.
