Brnovich v DNC - March 2, 2021 SCOTUS hearing
SCOTUS: "I'm interesting in knowing why the RNC is in this case. So you know, the DNC has standing and the District Court said that it had standing to challenge the out-of-precinct policy because the policy placed a greater imperative on Democratic organizations to educate their voters and because the policy harmed its members who would have voted out-of-precinct. What's the interest of the RNC here and keeping, say, the out-of-precinct voter ballot disqualification rules on the books?"
AZ GOP: "Because it puts us at a competitive disadvantage relative to Democrats. Politics is a zero sum game."
In other words, the GOP acknowledges they can't legitimately compete and win against the Dems in a general election - as their policies are widely unpopular by the majority of the public - so need voter suppression laws to disinfranchise those most inclined to support the Dems.
