Ben Roback: Johnson and Trump – digging in and clinging on

Both leaders are firing up their bases and seeking out all-or-nothing confrontations with their political enemies.

Gareth Lyon: Post-Boris. The Prime Minister is more Lyndon Johnson than his jokey former self.

And just like Kennedy’s successor, he must match a serious time with a focus on delivery, not just promises.

Dominic Walsh: What would No Deal mean for trade beyond the EU?

While trade deals have taken on an important political and symbolic value, their benefits are typically smaller and slower to materialise than many realise.

Ben Roback: The racism row. Trump has set a trap for the Democrats – but risks also falling into it himself.

The White House attack on “the squad” risks turning out Democratic voters as a natural by-product of seeking to turn out Republicans.

Ben Roback: Was Trump the real winner of the first Democratic debates?

A confused and crowded field will ensure the President has plenty of ammunition to throw at whoever emerges to challenge him in 2020.

Lord Ashcroft: Candidates should listen to the voters’ backstory, not try to sell their own

The most successful are those who can put their values to work and build a broad coalition, rather than exploit divisions.

Ben Roback: The Democrats, gender, diversity, youth – and why Biden (76) may take on Trump (72)

By nominating him, they would be wagering a similar bet to the one they placed in 2016 when Clinton was selected as the safe candidate.

John Redwood: Why populists reject the establishment – and no longer believe what it tells them

Here in Britain, the two main parties are being punished by voters for tearing up their Brexit commitments.

Ben Roback: Democrats risk overplaying their response to the Mueller investigation

Obsessing with a Washington debate about impeachment is a gift to the President, who repeats a far simpler message.

Iain Dale: The Conservatives treated Widdecombe with disdain. They will pay the price in lost votes next month.

Plus: Creepy Biden, useless TIGs, spineless Tory MPs…and why I’d favour Scottish independence were I fully Scottish.

Ben Roback: Trump’s state visit. Problems abound. But interests – trade, defence, the Special Relationship – endure.

The visit should serve as a timely reminder that the last especially outlasts any individual President or Prime Minister.

What do and don’t we know about Mueller’s investigation, the Trump campaign, and Russian interference?

Cutting through the fog of war and spin can be tricky, but here are the fundamental facts so far.

Lord Ashcroft: “There’s not going to be a single Democrat that can go toe-to-toe with the President.” My interview with Kayleigh McEnany.

Trump’s press secretary sets out how the President intends to run his re-election campaign in 2020.

Ben Roback: Can a true progressive win the presidency in 2020?

Hopefuls should remember that what plays well in the primaries may be un-deliverable from the White House.

Sanders is a refreshing change from the careerists who infest American as well as British politics.

So though he presents himself as anti-Trump, he has something in common with him. And there could, astonishingly, be a future for socialism in America.
