With Bushco, the route to take would not have been to go straight for Bush and Cheney, but to start with the small fry (contractors delivering shoddy work, rampant waste, positions filled with people far too inexperienced to do the job they had but were chosen because political connections, etc.) in order to publicly associate Bush with a big stinking cloud of corruption. Get people pissed off at Bush because their sons couldn't use a shower without wondering if they'd get electrocuted. Once a big stink is laid at their feet, you can bring the public along for higher-level stuff.
But it's something that needs to be pushed, not just "put out there" with the expectation mainstream media will pick it up and run with it. They won't, because that would be "liberal bias." This is why the conservatives built their own media machine: to push their narratives, whether that involves advancing their agenda or defending against accountability for malfeasance.
So no, there won't be any indictments handed out on Jan. 21, but the extent of the corruption needs to be dug into, exposed, and made public. But yes, after investigations and cases made, there do need to be prosecutions. I don't share your view that we would have taken a massive loss back then if the Republicans had been publicly connected to corruption instead of being able to claim is was all hot air and politics. The same now. It's ignoring what they did in the name of "healing" that will cost us -- and it will prevent real healing.
