Story highlights Kanye says he didn't vote, but would have voted for the controversial Republican candidate

Declaration leads to scathing criticism from fans -- and former fans -- on social media

(CNN) Could this be a very early campaign stunt?

Hip hop superstar Kanye West, who famously declared his intention to run for President in 2020, told a shocked audience in California that he didn't cast a vote in the presidential election earlier this month, but if he did, he "would have voted for Trump."

After the slightly-too-late endorsement for Donald Trump, the shock winner and now-President-elect, given between songs during the show at the SAP Center in San Jose on Thursday night, a large section of the audience booed the singer.

The moment was captured from afar by one concert-goer. While the majority of the crowd boos, one audience member can be heard clapping.
