The poor judgement expressed in the article may just be an indicator of why Dean ended up in so much trouble back then.
I don't see how being supported by Fox News would have kept the grand jury from identifying Nixon as an unindicted co-conspirator, which, as I recall, was the case. Nixon mused that raising hush money to conceal the conspiracy could be done. Nixon was an arrogant jerk and deserved what happened to him and then some.
To this day we don't know what was on the 18-minutes of erased tape. It must have been pretty damning to obstruct justice so blatantly. And yes, I believe it is possible for a President to obstruct justice. The executive branch is not the sole arbiter of what constitutes "justice".
Dean is, and was, a craven, sniveling scumbag. He has lived and will die with that.
Such is the life of a quisling. The right abhors him, and the left despises him.
