When the time comes, you will know what to do. Seriously.
Watching the clips of *'s public appearances over the past few weeks, it seems clear he's coming unhinged. He wasn't all that tightly wrapped to begin with, and who knows what sort of a delusional state he's in right now? Or how he will react.
The GOP and the Religious Right and the Corporatists and the Neocons have been having their merry fun for some time now. They are all using each other to try to gain the upper hand. Some of those alliances will be breakable under the right conditions.
What we don't know are what will constitute the right condition to break any of these alliances. So I have to agree with the poster above: keep pressuring your elected representatives, the press, and anybody else in power in any legal and peaceful way you can dream up.
I don't know if the dam will suddenly overflow or if we're going to have to worry those small cracks open.
When we get a clear opening, however, what needs to be done will likely be clear.
Until then: courage.
