The revelations of the past week are dramatic and exciting for those who really want to get at the truth about what happened during the 2016 election. Nevertheless, they could have a down side.
My main concern is that some anti-Trump people might be staking too much on evidence turning up of direct collusion between his campaign people (Manafort et al) and the Russians to influence the election. It's one thing for them to have been in touch with the Russians, and it's another thing for the Russians to have "hacked" the election, but the Russians might have been too smart (they are much smarter than Trump and his boys) to leave any traces that this was coordinated. In fact it didn't need to be, the Russians just could have been working all the angles.
I'm not saying this is the way it was, but if it turns out that way then the investigations are going to fizzle and the Trumpists will be able to claim there was never anything serious there. It's all fine to be focused on it as long as it does not distract from the need to build a mass movement that will have impact on the streets, and in the voting booth late next year (that's still a long way off.)
Unfortunately, too many Democrats hate doing anything that might involve actually changing anybody's mind about political questions. Instead most establishment Demos prefer to slosh donor money around, build machines, and focus on voter turnout, rather than influence political views. The "return" of Hillary Clinton to political life is a bad sign that way--she represents the very worst of Democratic Party machine politics.
