That’s excellent thinking.
I don't think anybody would say that Pence was not a "reasonable" person. If Pence said he "share[d] the concerns of millions of Americans about voting irregularities" then it's not unreasonable for President Trump to say that he, too, shared those same concerns on January 6th and believed that he actually won the election.
This is enough to throw out Smith's latest indictments.
