Bob Dole (He ain't no pineapple)

Well, this is perhaps why Bob Dole never made it to the White House; his campaign slogan wasn't exactly magical. But check out this Web site - www.retropresident.com - selling T-shirts with old Presidential campaign slogans.
Who can forget "Nixon: Now more than ever" or "I like Ike."

TK: This year, Iowans have seemed to endorse "I like Mike." Here is a nice link to a history of all presidential campaign slogans.
