When will a decision on the Texas case be made?
Potentially as early as this time tomorrow if (as seems likely) SCOTUS is as disinclined to touch it as they were to touch the Kelly case.
Yeah, there's obviously no set timeline or anything, but they're definitely gonna decide pretty quickly. The deadline for PA to respond in Kelly's case, for example, was at 9am yesterday & the Court had already denied by mid-afternoon, right after Kelly replied to PA's response (I think the time in between was ~34 mins.). With the respondents in the TX case - PA, GA, MI, & WI - being given a deadline of tomorrow at 3pm to respond, we should get a decision sometime Friday if the same timeframe holds, which makes sense, given that the Court has a conference meeting on Friday morning at which I presume this will be a topic of discussion.
Of course, it's also possible that the Court could deny even prior to Friday, given how rapidly they denied injunctive relief in Kelly's case. In any event, though, they're definitely gonna get it done before the Electoral College votes on Monday.
