Portugal Colonial - Robert F. Kennedy Jr suspends fringe White House bid

"I no longer believe that I have a realistic path of electoral victory," Kennedy, an anti-vaccine activist and conspiracy theorist who was polling in the low single digits, said at a press conference in swing state Arizona.

Kennedy, 70, condemned the selection of Vice President Kamala Harris as the Democratic standard-bearer without a primary contest and cited a long list of grievances against his former party that he said had led him to now "throw my support to president Trump."

Kennedy's independent candidacy featured a number of bizarre stories -- including about suffering from a parasitic brain worm and depositing a dead bear cub in Central Park -- and drew the opposition of most of his famous family, who threw their weight behind the Democratic ticket.

"Our brother Bobby's decision to endorse Trump today is a betrayal of the values that our father and our family hold most dear," his sister, human rights activist Kerry Kennedy, said on X.

"It is a sad ending to a sad story," said the statement, also signed by four other siblings.

Kennedy's withdrawal came a day after the surging Harris gave an electrifying speech in Chicago, accepting the Democratic presidential nomination and embarking on the final 10-week sprint to election day.

Analysts are mixed on the effect Kennedy's exit will have on the presidential race and how much of his support will gravitate to Trump or Harris.

However, in a very tight contest, it is possible that even a few thousand votes in a crucial swing state could determine who wins the White House.

Harris and Trump are neck and neck in the polls less than three weeks before their September 10 debate in Philadelphia.

- 'On to tomorrow' -

Harris, a 59-year-old former senator and prosecutor, left the Democratic convention in Chicago with momentum, having outraised Trump and erased the polling leads he enjoyed before she replaced President Joe Biden on the Democratic ticket last month.

But she is not resting on her laurels.

"On to tomorrow," she told NBC News after the speech. "That was good -- and now we've got to move on."

Dan Kanninen, battleground director of the Harris campaign, cautioned that the race remains "very, very tight."

Harris accepted her party's nomination Thursday on a glitzy final night in Chicago to set the stage for the grueling run-in to November 5.

In just a month, Harris, the first Black woman to top a major party ticket, has raised a record-breaking half a billion dollars, enjoying a political honeymoon that shows little sign of ending.

Her campaign got another potential boost Friday when Federal Reserve chair Jerome Powell said the "time has come" for an interest rate cut -- something which will lower mortgage costs and other inflationary pressures for voters.

Potential headwinds for Harris include internal party tensions over US policy on the Israel-Hamas war and fallout from Kennedy's withdrawal.

Democratic heavy hitters, from Michelle Obama to Bill Clinton, warned that the party could still lose to Trump's Republicans if complacency creeps in.

"If we see a bad poll -- and we will -- we've got to put down that phone and do something," the former first lady told the party faithful in Chicago.

- 'Unserious' -

Trump, 78, has been mobilizing his right-wing base with apocalyptic warnings about migrant criminals and painting a dark picture of a country in "decline" that only he can save.

Harris and her Democrats have been reaching toward the center.

"If you vote for Kamala Harris in 2024, you're not a Democrat, you're a patriot," former Georgia lieutenant governor Geoff Duncan said.

While they previously characterized Trump as a demagogue, Democrats have instead begun making fun of the Republican nominee in a manner designed to belittle him and dent his aura of invincibility.

Harris called him an "unserious" person.
