So investigate all those aspects. But don't call it an impeachment campaign. Call it gathering facts. And if those assertions pan out, as Mick says it may emerge that Cheney should be impeached, convicted, and removed. And by then, if you convince the general public of this, as Mick also says, there may be enough pressure to be able to impeach and convict.

But when the Republicans impeached Clinton they did themselves no favor. They realize that now.

If you can't both impeach AND CONVICT, you've wasted your time, taxpayers' money--and alienated the electorate.
