Republican presidential nominee Donald Trump has received some of his worst criticism from Hollywood elites — from late-night show hosts making cheap jokes at his expense to celebrities dishing in interviews about him.

Just this week, Will Smith, that intellectual heavyweight who is married to Jada Pinkett Smith (whose “open marriage” has been the subject of stories for years) attacked Trump in a published interview.

The onslaught of negativity from artists has done little damage to Trump’s popularity.

“For a man to be able to publicly refer to a woman as a fat pig, that makes me teary,” Smith said in the piece, published online at news.com.au. “My grandmother would have smacked my teeth out of my head if I had referred to a woman as a fat pig.”

He added, “For me, deep down in my heart, I believe that America won’t and we can’t [elect Trump]. Of all the things he has said, and we could go through the laundry list, that was the one that was such an absolute illustration of a darkness of his soul. I just cannot figure out how people can clap for that.”

The onslaught of negative vibes from artists has done little damage to Trump’s armor.

But that isn’t stopping Hollywood from continuing to wage war against Trump. More than 100 celebrities have signed a Moveon.org petition called “United Against Hate,” vowing to do everything they can to prevent a Trump victory in November. The group declared their plan to “use the power of our voice and the power of our vote to defeat Donald Trump and the hateful ideology he represents.”

Signers of the petition include Samuel L. Jackson, Kerry Washington, Lena Dunham, Shonda Rhimes, and musician Macklemore.

But so far, celebrity has not counted for much this political season, amounting to little more than whimpering or pouting, depending on the celeb. While Obama rallied Hollywood elites around him in both his presidential elections and benefited greatly from the financial and cultural support, celebrity Trump haters face one giant obstacle this season — Hillary Clinton.

Did you see the very grumpy, Sanders-loving Susan Sarandon at the Democratic National Convention?

Clinton has not only been unsuccessful in drumming up the same Hollywood help as Obama — even her supporters can’t give her full-hearted endorsements. Petition signer and Youtube star Laci Green said, “To defeat Trump, we need to get people, and especially young progressives, to actually vote in spite of frustrations with Clinton.”

Other petition signers don’t even have much faith their own voices can make a difference this election. Documentary filmmaker Michael Moore is a signer of the “United Against Hate” petition — and yet just recently penned a blog entitled, “5 Reasons Why Trump Will Win.”

The fact that the petition comes from moveon.org also speaks volumes about the elitism Hollywood celebrities practice in politics. The group was originally formed in 1998 to stop the impeachment of Bill Clinton. The group has since been funded by progressive billionaires like George Soros and has worked tirelessly to push progressive politics onto the American people.

Ironically, the group itself is not even a strong supporter of Hillary Clinton — they originally endorsed Bernie Sanders. Though Trump’s popularity may not take a hit from celebrities who vow to use their public standings to stop him, the group shouldn’t be underestimated. They spent tens of millions of dollars to get Obama elected in both 2008 and 2012.

The fact that the group has taken responsibility for violent and disruptive protests against Trump is an example of the hypocrisy these celebs probably won’t take into account.

The “United Against Hate” movement is certainly nothing new for Trump. Univision published a letter signed by many prominent Hispanics that took a stand against Trump. Author Stephen King led voices in an open letter from 400 authors cementing the fact that none of them would support Trump as “a matter of conscience.”

The real issue with celebrity influence this election cycle is not about any celebrity arguments against Trump — but rather, their support of another candidate, one with a pathetic political history and high unfavorable ratings.

Celebrities lose credibility in name-calling Trump while they stand by Hillary Clinton — a politician many feel is responsible for the deaths of four Americans in Benghazi in 2012 and who proved herself above the law and lacking in honesty during her Emailgate scandal. And those two examples are merely the tip of the iceberg.
