Volkswacht Bodensee - Harris and Trump race to US election photo finish

Less than three weeks before the presidential debate between the US vice president and the Republican ex-president -- and only a month before early in-person voting begins – polls show the race for the White House is neck and neck.

The former senator and prosecutor leaves Chicago with the wind in her sails, having outraised Trump and erased the polling leads he was enjoying before she replaced President Joe Biden atop the Democratic ticket last month.

But Dan Kanninen, battleground director of the Harris campaign, cautioned at a Bloomberg event on the sidelines of the convention that the race "is not fundamentally changed" and still "very, very tight."

"We have tremendous enthusiasm -- I think momentum is on our side -- but we now need to do something with it and engage the electorate effectively this fall," he said.

Harris accepted her party's presidential nomination on a glitzy final night in Chicago, buoyed by a galaxy of stars, that set the stage for the grueling run-in to November 5.

- Razor thin margins -

The 59-year-old Californian has edged ahead by razor-thin margins in polling, reversing what had started to look like a likely Trump victory against Biden before he dramatically pulled out and endorsed Harris.

In just a month, Harris has raised a record-breaking half a billion dollars, enjoying a political honeymoon that shows little sign of ending.

Party leaders have cautioned that headwinds could still buffet the campaign, however.

These include internal protests over US policy on the Israel-Hamas war and possible shifts in polling with the expected withdrawal on Friday of independent candidate Robert F. Kennedy Jr, who may endorse Trump.

The controversial scion of America's revered Kennedy clan is planning an announcement in Arizona, while Trump is also campaigning in the state, and promising to showcase a "special guest."

Analysts are mixed on the effect a Kennedy exit would have.

He is polling in the low single digits and his embrace of conspiracy theories has made him a fringe figure.

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

Democratic heavy hitters, from Michelle Obama and Bill Clinton to vice presidential nominee Tim Walz, have 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.

Walz, a former school football coach, used a sporting analogy, saying that Democrats were "down a field goal, but we're on offense and we've got the ball."

- Reaching for the center -

Trump has largely been singing to the choir, 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.

Party strategists spent the week in Chicago showcasing a parade of anti-Trump Republicans, including ex-cabinet officials, a small-town mayor and a former statewide office holder.

"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.

Harris, who has no events announced for the weekend, heads back to Washington with Second Gentleman Doug Emhoff on Friday to begin sketching out a battle plan for the next 70-plus days.

"I will be a president who unites us around our highest aspirations," Harris said in her keynote speech, earning uproarious applause.

"A president who leads and listens, who is realistic, practical and has common sense and always fights for the american people."
