Obama was a rising star. Liz being promoted as a rising star is only is a headline shock by publications to the left.
Your narrative that Liz Cheney was only a star to Democrats and the media is false, and it is very easily rebutted by established facts.
(1) Rep. Liz Cheney was a Conference Chair in the Republican Party House of Representatives. She was removed from that leadership post last May, just because of her vote to impeach Donald Trump.
(2) Rep. Liz Cheney has never had a close election in the state of Wyoming. 17 points is as close as anyone has ever come to her over the course of 3 election cycles. However, she will be soundly defeated in the 2022 Republican Party Primary, just because of her opposition to Donald Trump's conduct.
