Political junkies who have felt adrift since the end of the presidential campaign should make their way to Dallas this month, where three exhibits will help fill the void. At Southern Methodist University’s Bridwell Library until January 20, “From George to George: Presidential Elections in the United States From 1789 to the Present” puts to rest questions like what the average length of a soundbite is (7.2 seconds) and why Jimmy Carter’s advisers resisted campaign buttons (leisure suits had no lapels—and besides, it was cheaper). Through January 30 at the Sixth Floor Museum at Dealey Plaza, “The Living Room Candidate: A History of Presidential Campaign Commercials, 1952—2004” presents the most effective, and notorious, political ads ever made, such as the “daisy girl” commercial from LBJ’s 1964 campaign. And at the Women’s Museum through February 13, “First Ladies: Political Role and Public Image” charts the shifting definitions of womanhood in the White House through artifacts like Mary Todd Lincoln’s tea service and one of Hillary Rodham Clinton’s signature black pantsuits.
