For almost 8 years, many democrats (or just loony liberals) called for the impeachment of Bush. The reasons were never substantial, the main one being they just could not stand him (probably because he beat Al Gore for President). But even with significant majorities in both houses of congress during the last 2 years, there was no serious movement by democrat leaders to carry out the impeachment. Why?
There was no impeachable offense, just offensive policies.
12 years ago, a president was impeached, but not removed from office. it was only the 2nd time in history that had been done, the first being a republican. And that was a legitimate impeachable offense, albeit it had nothing to do with his job performance. But that is the issue. Impeachment is the vehicle to make sure the president is not above the law. 36 years ago, a president resigned instead of facing impeachment, not for anything he did related to the office, but for crimes committed that anyone else would have gone to jail for.
Today, we are approaching another impeachable moment. As the Sestak scandal continues to unravel, it is clear that at the least some bad judgment was used in trying to maintain the democrat majority. At worse it is a crime. But that is not what is going to catch Obama. for it seems in order to protect his nascent administration, the administration is trying to cover up the dealings.
So what you ask? I am sure many democrats are shouting that right now. No crime, so no cover-up. Au contraire! There was no underlying crime that got Scooter Libby in hot water, but he was convicted of "obstruction of justice" - a cover up in other words. The same thing that got Nixon out of office (it was never even reliably alleged that he had anything to do with the actual crime there either).
You would have thought that after Watergate (that gave us all subsequent gates apparently), Politicians would have learned. Clinton did. He actually committed a crime, but when it came to throwing his staff under the bus, he was without peer. But Obama does not seem to be that smart. He seems bound and determined to repeat the mistake of Nixon.
Whether he was in on the bribe to Sestak or not, is irrelevant now. What is apparent is that his administration is in rapid CYA mode to cover it up, and the stench goes all the way to the Lincoln Bedroom.
Nixon screwed up after 4 years, Clinton 6. It has taken Obama less than 1 1/2. He may not be smart, but he sure is fast.
