Are the Swedish democrats still too toxic to be included in any possible goverment ?
Not really, I believe. The Moderates, Liberals and Christian Democrats have a "collaboration agreement" with SD and they have presented some conjoint policies. Not sure if they will be part of a coalition government, but SD will support a proposed Moderate PM and, unlike 2018, M-L-KD will accept that support.
Yeah, M-L-KD-SD are basically the right bloc now, M and KD had already been on board with an SD backed government and then around a year ago, the Liberals left the current centre-left government and said they’d be okay with a government supported by the Swedish Democrats.
