"I'm a Republican voting for Mitt Romney/You lazy [expletive] is [expletive] up the economy," she raps in the single.
Many people were outraged that the artist would support Romney and not Obama.
"Dumb [expletive] nicki fans still? gonna support her -- that's the sad thing. Like [expletive] a few years ago u were in the same situation see how money changes people? Yeah she forgot where she came from," wrote one YouTube user.
Obama, however, seemed to understand Minaj's lyrics perfectly. When asked about the song, he told radio show hosts Obie and Lil Shawn during a phone interview this week:
"I'm not sure that's actually what happened. I think she had a song on there -- a little rap that said that. But she likes to play different characters, so I don't know what's going on there."
Minaj confirmed the Obama's doubts on Twitter: "Ha! Thank you for understanding my creative humor & sarcasm Mr. President, the smart ones always do ... *sends love & support* @BarackObama."
In many of her songs, Minaj plays various personas. Minaj told Blackbook magazine in an interview last year, "I'm definitely playing a role. They don't pay to see me roll out of bed with crust in my eyes, and say, 'Hey guys, this is me, authentic.' They pay for a show."
If Minaj had been a Romney supporter, she would not have been the first eyebrowing-raising supporter of the Republican presidential candidate. Former porn star Jenna Jameson recently endorsed Romney. "When you're rich, you want a Republican in office," Jameson told CBS San Francisco. "I'm very looking forward to a Republican being back in office."
