Interesting thing about the decision - the 3 liberal justices were the ones dissenting.
The conservative majority said that this map should be used only for the election in November (because of their previous decisions that changes can’t be made this close to an election). That means the challenges to the map from right wing groups in the hostile lower circuit courts will come back after November and they will still have a chance to throw it out.
The liberals argued that the court would have ample time to consider the merits of the case (in light of the precedent they set in the nearly identical Alabama case) and order the map to remain in effect until the next census.
Lots of gamesmanship in the decision - but still good for Democrats in November (at least this year).
Can we still presume that black votes are necessarily going to go Democrat? There have been some weird minority voting outcomes in recent years, with e.g. Hispanic communities voting red despite the strongly anti-minority and anti-immigrant planks in the Republican platform. Democrats are more liberal on LGBTQ and pro-choice, and these are likely single-issue voters driven by religious decisions. We saw the same thing to a lesser degree in black communities, less starkly contrasted because of what’s at stake for Hispanic communities.
Is the evidence this is going to benefit Democrats?
