Fair, but it’s not like she’s the first person to go from smearing a primary opponent to endorsing him or being his running mate. I also don’t think her attacks on Biden during the primary were that brutal - it’s not like she accused Joes dad of assassinating a president or said that Joes wife was ugly.
Like I said, Kamala’s hands are pretty clean if this is the best they can do. The real issue is that all the skeletons in Kamala’s closet are from her days as AG, and a president running on “law and order” can’t criticize the other side for being too in favor of law and order.
