hot take: the reason SCOTUS is sort of leaving the PA case open is because Dems have returned their ballots at such a high rate and are so educated on the issue that the majority of late ballots might actually be REPUBLICAN.
No the reason SCOTUS is doing it differently in PA is because its a State court that ruled in a sh**tty manner rather than a lower level federal court as in Wisconsin.
In PA the state supreme court court is very D, while in WI its 3 R hacks, 1 non hack R, 3 Hack Ds. Hagedorn would not make up random law so Ds didnt sue in state court for Wisconsin. In WI due to it having 2 D senators until 2010 and the method of blue slips its district courts are quite liberal leaning. PA is the opposite as until 2006 its had 2 GOP senators. Scotus is less likely to overturn state law or a state supreme court ruling while there is 0 respect involved for a low level federal judge making a sh**tty ruling.
I like how atlas assumes hackery on all these SCOTUS cases when the R majority blocked an independent redistricting commission on Oregon in a similar case. An Emergency does not give federal judges the right to unilaterally change state law .
