Fox News regular and famous-for-being-famous person Meghan McCain offered conservatives a new argument for supporting Donald Trump. Likely Democratic nominee Hillary Clinton, she told Neil Cavuto, is "truly evil."

"But you still prefer him over Hillary Clinton?" Cavuto wondered.
"I told you, a tuna sandwich over Hillary Clinton," McCain quipped. "Because I think Hillary Clinton is truly evil, and she's truly a liar and she's been responsible in my opinion for getting people killed."
"Come on," Cavuto replied.
"She's Darth Vader," McCain insisted. "I can't trust her in any way."

Ms. McCain would have done well to check in first with her father before trashing Secretary Clinton. Leave aside for the moment that daddy was catastrophically wrong at almost every point about the invasion of Iraq and the bloodbath that followed. As it turns out, Senator John McCain has said of the former First Lady, "I'm proud to call her my friend" and "I have no doubt that Senator Clinton would make a good president."
As the New York Times (2006) and the Los Angeles Times (2008) documented, the almost presidential rivals had a close relationship during their days in the Senate. That's all the more surprising given John McCain's grotesque joke at the expense of a young Chelsea Clinton in 1998:

"Why is Chelsea Clinton so ugly? Because her father is Janet Reno."

(The self-proclaimed "bad boy" did apologize to President and Mrs. Clinton, but not to Janet Reno.)
Nevertheless, as the New York Times reported in July 2006, the Senators from New York and Arizona developed a bond after the former First Lady's Election:

Two summers ago, on a Congressional trip to Estonia, Senator Hillary Rodham Clinton astonished her traveling companions by suggesting that the group do what one does in the Baltics: hold a vodka-drinking contest.
Delighted, the leader of the delegation, Senator John McCain, quickly agreed. The after-dinner drinks went so well -- memories are a bit hazy on who drank how much -- that Mr. McCain, an Arizona Republican, later told people how unexpectedly engaging he found Mrs. Clinton to be. "One of the guys" was the way he described Mrs. Clinton, a New York Democrat, to some Republican colleagues.
Mrs. Clinton and Mr. McCain went on to develop an amiable if professionally calculated relationship. They took more official trips together, including to Iraq. They worked together on the Senate Armed Services Committee and on the issue of global warming. They made a joint appearance last year on "Meet the Press," interacting so congenially that the moderator, Tim Russert, joked about their forming a "fusion ticket."

In June 2008, Republican water carrier Andrew Malcolm described the "the secret friendship of Hillary Clinton and John McCain." While his campaign (which said Senator Clinton "ran an impressive campaign" and was "an impressive candidate" that "inspired a generation of women") was motivated to peel off voters frustrated by her primary loss to Barack Obama, Senator McCain nevertheless gave Hillary a ringing endorsement:

"Sen. Clinton has earned great respect for her tenacity and courage. The media often overlooked how compassionately she spoke to the concerns and dreams of millions of Americans, and she deserves a lot more appreciation than she sometimes received.
"As the father of three daughters, I owe her a debt for inspiring millions of women to believe there is no opportunity in this great country beyond their reach. I am proud to call her my friend."

This not-so-distant history seems to have eluded Senator McCain's daughter. It's certainly not the first time. In June 2009, Meghan McCain appeared on Real Time with Bill Maher to protest that President Obama blamed his predecessor George W. Bush too much for the nation's woes. When fellow panelist and Clinton ally Paul Begala pointed out the Ronald Reagan savaged Jimmy Carter throughout his 8-year tenure, Ms. McCain quipped. "you know I wasn't born yet so I wouldn't know." That's when Begala brought the hammer down:

"I wasn't born during the French Revolution but I know about it."

But Meghan McCain was alive in November 2011 when she urged an Obama/Clinton ticket because Hillary "is a woman who kicks ass in politics" and in May 2014 when she said Karl Rove's comments about the Secretary were "disgusting." So what's her excuse now?
