"Isn't it amazing how 'not cool' it is to be conservative in the public eye?" Palin wrote in the blog post. "Either Hollywood is that far off — or we have so many sissies we have in the spotlight too scared to stand for what they believe in!"
Among her targets was Elton John, who she said attacked American country music by suggesting that a country artist would be willing to play for Trump. She called the perceived slight "surprising considering (Elton John) stole all their rhinestone outfits."
She also slammed the DJ duo The Chainsmokers, who have been nominated for three Grammy Awards and joked earlier this month about performing for Trump, as being irrelevant anyway.
"Don't worry," she wrote. "I haven't heard of them either."
She named the band KISS' refusal to play as "perhaps the most surprising" announcement, considering Trump's "larger-than-life persona" and KISS' "explosive stage show."
"(They) would've been a match made in heaven," she wrote.
However, the band refused.
"This is what's great about America: You're allowed to say no," Palin wrote. "And these A-listers declining the invitation has opened up a chance for someone who really needs it."
She ended her post on a high-note, highlighting Evancho's decision to perform on Jan. 20.
"So far, that might be her best decision yet," Palin wrote.
