a post-Trump GOP, with a more moderate political stance, would be a brilliant thing.
The Democratic Party is not really friendly to the UK. It's mostly anti-Brexit, pro-EU and slants towards a sentimental Catholic view of Ireland. Biden is fairly typical. So is Pelosi.
The GOP has often been more constructive, valuing the alliance.
I do hope the GOP moves away from the Gingrich-Trump madness and back towards the centre, so that they are less likely to upset the domestic American applecart.
