Sneaking in a political bombshell before the end of the year, Donald Trump has been banned from running for president in the state of Colorado. It goes back to the 14th Amendment to the US Constitution, which bans people from office if they’ve “engaged in insurrection”. And in a 4-3 decision, Colorado’s Supreme Court yesterday decided that Trump had done just that on 6 January 2021. So what’s Colorado got to do with it? America’s system of voting on a president means each state has its own rules… But analysts say the Colorado ruling could be applied to the whole country (or else quashed entirely…) when the case heads to the nation’s Supreme Court, which is where Team Trump will bring an appeal. Democrats were cockahoop about the decision yesterday, but others (including Trump critics) say it could help Trump by galvanising voters who don’t like ‘the government’ ganging up on him.
