If you want to know what happens if she and Marine Le Pen in France get the power,

So:

• In the US, Trump's last year is 2028. Mind, Vance has generally been considered to be the most-likely Republican nominee and is isolationist, but I don't know how well he'd do, given Trump's now-very-high unpopularity and his association with the Trump administration. Rubio, who I've seen listed as being the second-most-likely Republican nominee, is a lot more conventional, and I'd assume that any Democratic president would likely also be. 2028 elections are still a long way out, so hard to make many calls yet.

• In the UK, while Reform topped polling for a while, Labour has finally managed to pull a little ahead, and the Conservatives look to me likely to do so as well. So my guess is that the likelihood of Prime Minister Farage is on the downswing.

• In France, RN (run by Le Pen) presently holds a large polling lead. LFI (run by Mélenchon) just crept ahead of ENS (run by Macron). Elections are only about six months out.

• In Germany, AfD is polling on top. The next federal election may not happen until as late as 2029, however, so it could be quite some time away.

  My understanding is that the German political system can theoretically hold a party with a plurality but not majority of votes out of executive power if everyone else chooses to do so; this is known as the cordon sanitaire. In the past, this had by convention applied to far-right parties. However, I don't know whether this will continue to hold.

  A strict political non-cooperation is only exercised against right-wing parties, such as the Republicans, and even the Republicans have exercised a cordon against the neo-Nazi The Homeland. Since 2013, the established major parties have refused to form state-level coalitions with the new right-wing populist party Alternative for Germany (AfD). Brandmauer (firewall) is the term most often used in Germany to refer to this non-cooperation policy against the AfD.[24]

  In February 2025, the Christian Democratic Union of Germany put forward a non-binding motion, taking AfD votes into account, in the Bundestag to push through a on the detention of undocumented foreigners at borders. This was the first time since 1945 that the cordon sanitaire had been broken in Germany. This event provoked large-scale demonstrations across Germany, with between 160,000 and 250,000 people in Berlin on February 2, and over 220,000 demonstrators in several of the country's major cities the day before.[25][26]
