Did russian agents illegally vote in any states? Otherwise I don’t think they meddled anymore than you could say England meddled because BBC news ran an Anti-Trump news story.
You really don’t want to open up the topic of illegally voting. Once you do that...we go to a national ID card, double-checking state poll listings, etc. Dead people come off....illegals fade away....college kids voting in dual states would stop. Yep....you just don’t want to suggest that Russians voted.
