Eh, I see it, at least given how it's been explained to me, as a signal. Much as the metal detector doesn't automatically mean there's buried treasure at play, this doesn't mean there's fraud.
But I wouldn't consider it looked into until you get a shovel and check.
As to whether or not things have coalesced, I'd say certainly more has.
For example, it seems to be an objective fact at this point, Republican poll watchers and observers were prevented from doing their job, thanks to numerous testimonies, recordings, audio, and photos of these events.
That alone strikes me as a major sign of significant corruption. Certainly, it provides more than reasonable cause to doubt the integrity of the election.
And there's been a lot more stuff brought up in the various hearings, besides. Some with pictures, some with videos.
A recent one where they tell everyone they're done counting for the day, telling poll watchers to go home, before pulling out a mass of ballots is pretty damning to me.
And of course, it must be mentioned, there was massive investigating and upheaval when it was Trump and the supposed Russians, so a refusal to investigate now is just downright hypocritical.
