Vice President Kamala Harris is the favourite to be the Democratic nominee for president after Joe Biden’s shock decision to drop out of the race - but can she really beat Donald Trump?

Some polls suggest Kamala Harris is even less popular than Joe Biden, especially in the crucial swing states and like president Biden - she’s stumbled a few times in public - leading some to write her off - but has she been totally underestimated?

To discuss all this and more, Matt Frei was joined by Christina Emba, staff writer at The Atlantic, and Channel 4 News’ International Editor, Lindsey Hilsum.

An assassination attempt, J.D. Vance - a relatively unknown Ohio Senator - picked as Donald Trump’s Vice President, and current President Joe Biden desperately clinging on to his own nomination - it’s been another huge week in American politics and there's still one day left at the Republican National Convention where Donald Trump is due to speak - so what will happen next?

We’re in Milwaukee where amongst the sea of red MAGA 2024 hats, some delegates are sporting fake white bandages on their ears - a nod to the injury that Trump sustained on Saturday night’s shooting.

Millennial Vice President hopeful J.D. Vance has made his first speech to the nation and reaffirmed his loyalty to Donald Trump - a change since reportedly calling him ‘America’s Hitler’ eight years ago.

But has the assassination attempt actually helped Donald Trump on his campaign? Will President Joe Biden definitely be the Democrat standing against him? And what’s the deal with all this new-found unity?

To discuss all this with Matt Frei on the first episode of The American Fourcast is Republican strategist Cassie Smedile, Washington Post reporter Azi Paybarah, and Channel 4 News’ Washington correspondent Siobhan Kennedy.

After a week-long victory lap in the UK, Sir Keir Starmer flew to America for the Nato summit where he met US President Biden and Ukraine’s president Zelenskyy - but his Western allies have been in a less celebratory mood than Britain’s new prime minister.

The far left and right are resurgent across Europe with France politically paralysed after Emmanuel Macron’s snap election gamble, while Joe Biden’s presidency is in near meltdown as Democrats turn on him after his disastrous debate with Donald Trump.

With wars in Ukraine and the Middle East threatening to spill over - the stakes couldn’t be higher.

So, how shaky is the Nato alliance right now and are the strains a sign of a wider decline in the West? The UK has a fresh-faced prime minister, but does it have any fresh ideas?

To discuss all this and more on this week’s episode of The Political Fourcast Krishnan Guru-Murthy is joined by Liberal Democrats’ Mike Martin MP, Labour’s Mike Tapp MP, and Karin von Hippel, the director-general of the Royal United Services Institute think tank.
