Well it definitely was until the odd timing of the Roe vs Wade decision. Knowing how politically charged this issue was, what was the impetus for the S.C to decide this at this time?
It may not change the mid-term outcome but it could soften the blow. Notice how many are blaming Trump for this, they want to try and stick any "less than dominant" midterm results on him.
Furthermore, Bush appointed judge Thomas, a family that is now more Democrat than GOP; comes out and suggests that "more could be coming" opening the door for more allegations by MSM and the Dems, accurate of not, that all types of laws could be overturned.
It's why I said immediately that it's vital for the GOP to get explain this decision to citizens because CNN and MSNBC are just going to politicize it and misrepresent the ruling.
The Neo-Cons don't WANT GOP to win the House, like all ideologues, their big donors would burn the nation if it lead to them grasping power again. The Dems had zero inspiration or momentum before this decision.
