It couldn't be more obvious that she was deliberately mocking the NA with her screeching way off-key rendition, particularly given the fact that she's so lunatic left as to pick a prominent member of the Amerifan communist movement to be her VP in her presidential bid. Shouldn't require much brain power to see and understand this.
Maybe you didn't actually see the video? If not, here it is again...
I’ve seen the video and stand by what I said. She wasn’t a singer, she isn’t a singer. She sang it “Roseanne” style or in “Roseanne” persona. They chose a comedian, expecting her to sing like Kate Smith or any other singer makes zero sense. They might as well have picked Carrot Top, I blame those who chose her.
As for her politics, whatever, it wasn’t like she was going to get any votes. She came to some sense in her older years when she backed Trump.
My brain power is fine, thanks. I don’t expect someone like Roseanne to sing like Whitney Houston.
