What was Fred Phelps' platform when he stood for election?

Fred Phelps formerly of Westboro Baptist Church, preacher and notorious bigot, stood for public office three times under the banner of the Democratic party. According to Wikipedia he convinced significant numbers of people to vote for him in statewide primaries.

Oddly, he had once been a prominent civil rights lawyer, good enough to get an award from the NAACP.

Did either his civil rights work or his homophobia feature in his campaign? If not, what did he say to persuade 50,000 people, 30%, to vote for him in the 1992 democratic Senate primary?

Edit: I have changed it to be clear, I want to know what his public prescriptions were, campaign promises... I do not want to know his private motives.

'Other than homophobia' was removed from the title. Fred Phelps is primarily known and condemned as a homophobe, and rightly so. I am not interested in that aspect of his campaign, just the other stuff. I already know he was a homophobe.
