The Creed frontman went on Fox & Friends on Tuesday (October 2) to announce that he will not vote again for President Barack Obama in the upcoming US election, but insisted that he is a registered Independent.
He said: "I'm just disappointed. I had very high hopes and expectations and was really inspired by President Obama.
"And I still am, he's an amazing speaker. But in my opinion, his administration [made] a lot of promises, but no real delivery."
He also said that it's difficult for him "to commit and to trust President Obama again".
However, Stapp did not say if he will be voting for Obama's opponent, Mitt Romney.
"My heart and soul would really love someone like Reagan or FDR to come back and give us a New Deal," Stapp said. "Be bold, be committed, don't care what anyone thinks. And when you tear down that wall, do it."
Obama and Romney are set to debate with each other tonight (October 3) in Denver, Colorado at 9pm ET.
Meanwhile, several female celebrities have come out to show their support for Obama.
Beyoncé, Jennifer Lopez, Julianne Moore and Olivia Wilde were among the famous names who appeared in a new campaign video that urges American women to vote for Obama and Vice President Joe Biden.
