Should we start adding a Trump effect to the polls and betting strategies?

Last November I wrote a piece pointing out the Conservatives were the 1/10 favourites to win the 2025 Canadian election. Whilst I was expecting some swingback I wasn’t expecting this level of movement but thanks to the Ayrshire hotelier has changed things.
When it comes elections and the betting therein we might have to factor things like this. Imagine Sir Keir Starmer calls an election for late 2028 which Reform are set to win and then Trump intervenes and sees Starmer recover in the polls, that might upset a few betting strategies and send people to the poorhouse.
