I would strongly advise against reading any American sources on what's happening in the UK (or let's be honest, any other country). Their explainers are generally written by people who just had it explained to them ten minutes earlier.
The BBC seems to be more or less adequate.
(Though to be fair, reading BBC analysis of political news in the US can also be a source of comedy.)
Generally speaking, the only value I find in checking US media on UK news (or the reverse) is to see how much a story has crossed over international lines.
