At this point whatever O'Rourke said about guns is irrelevant since the votes he needs aren't AR-15 fanatics and gun control will not be on the front burner. What will matter next year is Abbott's response to COVID, the abortion bill and the power grid failure. You also have to factor in that Abbott is seeking a third full term and that can be a hard sell with declining approvals.
You can’t say that Beto’s comments are irrelevant then bring out the power grid situation. That will be long history by November 2022 as well. That will not be an issue by then and long forgotten about. Last year there were awful consistent power outages in California during the summer with some areas not having power for 1-2 days and that was competent irrelevant in the California election.
