(CNN) -- Laura Ingraham is calling Meghan McCain a "useful idiot" and a "flavor of the month" - the latest salvo in the war of words between the conservative radio host and the daughter of former Republican presidential candidate John McCain.
"Memo to Meghan McCain: Enjoy the media coverage while it lasts, but know you're being used," writes Ingraham, in a blog post titled "'USEFUL IDIOT' WATCH." "You are the flavor of the month in left-wing media land because you are a Republican bashing the GOP. Likewise, your dad is most popular among the same people when he is slamming his Republican brethren in full-blown 'maverick' fashion. At least he backs up his views with a lifetime of sacrifice and public service.
Ingraham says liberals are taking a single satirical comment out of context "to paint Meghan as the victim of a right-wing hate crime" and "malign outspoken conservatives."
The radio host mocked McCain on her show last week over comments urging Republicans to seek compromise with Democrats. She referred to McCain “a Valley Girl gone awry” and a “plus-sized model.”
Ingraham calls the furor over her remark "manufactured and totally phony."
"This comes from the same playbook responsible for the ongoing demonization of Rush Limbaugh," she writes.
"If any off-the-cuff remark about a woman's size was condemnable, then where was the outrage when President Obama made a passing reference to Jessica Simpson's 'weight battle' during his Super Bowl interview with Matt Lauer?" she asked, referring to a headline the president noted on a magazine cover during his interview with the NBC anchor.
Ingraham pointed to digs Rush Limbaugh has gotten over his weight, and references to herself and Ann Coulter as "peroxide blondes."
(Update: John McCain responds after the jump)
"I laughed it off. If you can't stand the heat...get out of the punditry business," she writes. "Next time, just for fun, Meghan should pretend that she's had a change of heart and is now a pro-life conservative. Then she'll really see how the Mean Girls treatment feels."
Meghan McCain has taken aim at both Ingraham and Coulter over the past week during a media blitz that's included blog posts and appearances on network television.
On The View yesterday, she said she felt like model Tyra Banks, who “went on her show in her bathing suit and said, ‘Kiss my fat ass.’”
“That’s what I feel right now,” McCain said. “I’m like, ‘Kiss my fat ass!’”
Update: In a Tuesday afternoon interview with ABC's George Stephanopoulos on Twitter, Sen. John McCain repeated what seems to be his standard response to his daughter's string of headline-grabbing statements. "I'm proud of my daughter and she has a right to her opinions," he said, adding that "like any family we agree on some things and disagree on others."
