What makes you think Democrats are “focusing” on it?
Well considering Pelosi had a press conference about it today calling for more sanctions on Russia, it looks like the Democrats are going to make it an election issue.
Maybe I'm just cynical after the Mueller investigation, but I get the sense the general public now sees all Russia stories as "the boy who cried wolf" from Dems, and I think they would be much better served on keeping the focus on Trump's abysmal response to Covid. Don't hand him an issue where he looks like a victim.
