When then Senate Minority Leader Bob Dole was running for President back in 1987-88, he won the Iowa Caucus, beating both Vice President George H. Bush, who was considered the establishment candidate, as well as beating Reverend Pat Robertson who was the Christian-Conservative candidate. That made the 1988 Republican primary race for President a two-candidate field between Minority Leader Dole and Vice President Bush, giving each candidate a target to shoot at.
