At least some, maybe most of those challenges were dismissed on procedural grounds, lack of standing, etc. They never got to the point of examining the "evidence." Maybe the retort to that is the challengers should have foreseen that. But the people filing these challenges were not unhinged randos from Twitter. They were elected officials, lawyers, educated people. They aren't going to go into court with something they know is frivolous.
Given that a sizable minority (and likely unprecedented number) of the voting public thinks there was fraud in the 2020 election, maybe it would have been better to have rebutted the evidence rather than the process.
