PHOENIX, AZ - SEPTEMBER 27: Republican presidential hopeful Dan Quayle, with his wife Marilyn, speaks at a press conference 27 September, 1999, in Phoenix. The former US vice president, lagging in the polls and low on cash, quit the race for the Republican presidential nomination. Quayle said he did not have the campaign cash to compete with Texas Gov. George W. Bush, the Republican front-runner, whose campaign funds recently topped 50 million USD. (Photo credit should read MIKE FIALA/AFP via Getty Images)
