Well thats the thing, its hard to defend in politics. Defence means that you're allowing your adversary to set the terms of engagement. A functioning media can act as an arbiter/referee there that holds both sides to account when they depart from shared reality...but lol, its been a long ass time since the US had that. So message confidently and aggressively.
tbh this is probably more impressive than those couple days after Biden stepped down because much of that money was likely just delayed donations from people who wanted to donate dem but were hesitating to donate to Biden post-debate.
