Paperwork was filed on Wednesday to make official the declared candidacy of Robert F. Kennedy Jr. to seek the Democratic Party's presidential nomination in 2024, the Washington Examiner reported.

He joins spiritualist and self-help author Marianne Williamson as the only prominent Democrats, at least so far, to formally launch a bid to try and replace President Joe Biden as the party's nominee.

Biden himself has not yet officially kicked off his 2024 re-election campaign, but has previously expressed his intention to seek a second term in office and is broadly anticipated to make such a formal announcement in the near future.

Candidacy now official

The California-based Kennedy on Wednesday filed a "statement of candidacy" form with the Federal Election Commission to make official his intent to seek the presidency as a member of the Democratic Party and formally designated the Massachusetts-based Team Kennedy organization as his principal campaign committee for the 2024 election cycle.

That news wasn't a complete surprise, as Kennedy has hinted for more than a month that he was seriously considering a presidential bid, including in a tweet he posted on March 10 that included a link to his Team Kennedy website and solicited donations.

"If it looks like I can raise the money and mobilize enough people to win, I’ll jump in the race," he wrote.

Kennedy added, "If I run, my top priority will be to end the corrupt merger between state and corporate power that has ruined our economy, shattered the middle class, polluted our landscapes and waters, poisoned our children, and robbed us of our values and freedoms. Together we can restore America's democracy."

Fox News reported that Kennedy, during a recent visit to the New Hampshire Institute of Politics, hinted at the impending launch of his campaign when he told event attendees, "I’m thinking about it, and I’ve passed the biggest hurdle, which is my wife has green-lighted it."

Another Kennedy challenging another unpopular incumbent Democratic president

The Daily Mail reported that Kennedy is the son of the late New York Sen. Robert F. Kennedy Sr., the former U.S. attorney general who was assassinated in California in 1968 during a presidential campaign event. He is also the nephew of both former President John F. Kennedy, who was assassinated in Texas in 1963, and the late Massachusetts Sen. Ted Kennedy.

Interestingly enough, Ted Kennedy had similarly challenged an incumbent president for the Democratic nomination in 1980, Jimmy Carter, but was unsuccessful despite Carter's low approval ratings, a stagnant economy with high inflation, an energy crisis, and disastrous domestic and foreign policies.

Now another Kennedy is challenging the incumbent President Biden, who like Carter has had consistently dismal approval ratings and whose arguably even more disastrous domestic and foreign policies have contributed to persistently high inflation, a borderline recessionary economy, a global energy crisis, and a prospective third World War.

Vaccine skepticism a big issue

Kennedy's presidential bid is a long shot and, despite being a lifelong Democrat and environmentalist attorney, will likely curry little favor or positive coverage from the media due to his deep skepticism toward vaccines, as evidenced by how the Associated Press reported on the FEC filing from the "anti-vaccine activist."

He began to speak publicly about the potential health risks posed by vaccines to some individuals around 15 years ago and only grew more outspoken on the topic during the coronavirus pandemic in 2020 and beyond as he recommended against the new COVID-19 vaccines and instead urged people to treat infections of the novel virus with the off-label use of otherwise effective and proven drugs like hydroxychloroquine and ivermectin.

Kennedy has also been hugely critical of Dr. Anthony Fauci, the longtime director of the National Institute of Allergy and Infectious Disease who became the face of the federal pandemic response, and vociferously opposed mitigation measures like business closures, lockdowns, mask mandates, and of course, vaccine mandates.
