In his first rally for his last-minute presidential campaign, rapper Kanye West has ranted against abortion, argued policy with attendees and at one point broke down in tears.

West, 43, who has left voters befuddled over whether his campaign is genuine or a publicity stunt to help sell albums or merchandise, delivered rambling remarks at a Charleston, South Carolina, convention centre on Sunday.

In remarks that lasted just over an hour, he denounced abortion, swore, called on random members to speak and sometimes seemed to be putting forward policy proposals on the fly.

The event, which was livestreamed on YouTube and carried on local television stations, did little to clarify whether West is genuinely attempting to win the presidency.

The campaign he launched with a July 4 tweet has already missed several deadlines to appear on key state ballots.

West appeared on stage with “2020” shaved into the back of his head and wearing what appeared to be a military-style vest.

He argued that abortion should be legal but heavily discouraged, suggesting he would promote a policy as president that anyone who gives birth to a child be given $US1 million “or something in that family.”

West referred to the Bible and Christian teachings multiple times, and broke down in tears at one point while describing how he was nearly aborted by his parents.

“The only thing that can free us is by obeying the rules that were given to us for a promised land,” he said. “Abortion should be legal because guess what? The law is not by God anyway, so what is legality?”

The event carried few similarities with typical polished candidate events. The venue appeared to lack audience microphones, so West repeatedly told the crowd to be silent so audience members he called on could be heard.
