Democrats have given up all pretense of harassing law-breaking Republicans. They are now just arresting, charging, subpoening, and harassing Republicans for having the audacity to exist.
The House has ordered subpoenas for Harriet Miers, Alberto Gonzales, and Karl Rove. At least with the Scooter Libby trial, Democrats pretended that a crime was committed. Now, they are not even alleging crimes: they have their panties in a twist because Bush did something that they do not like:
Although the federal prosecutors serve at the pleasure of the president and are routinely replaced when a new president takes office, critics have charged that the firings were politically motivated and carried out in a deceitful manner that involved false claims of poor performance and misleading statements to Congress.
“At the pleasure of the President” means just that. Clinton fired all 93 US Attorneys when he took office; there is no better definition of “politically motivated.” If this is indeed a crime, what is the statute of limitations? If there is no SoL, or if it is greater than 14 years, why is the House not issuing subpoenas against the Clinton administration? If there is indeed some crime worth investigating, why have Democrats not at least referenced a statute? There is a Constitutional right to a probable cause determination before investigation and to be informed of the nature of the charges against oneself.
This should not be a surprise, though. As Sweetness & Light points out (with some phenomenal investigation and research), it was Joseph Wilson who outed his wife to high-level Washingtonians; Democrat Richard Armitage then leaked her name. Democrats then tried and convicted Scooter Libby for “crimes” related to the leak.
The witch hunt will continue until Republicans fight back. When they demand a list of crimes, applicable statutes of limitations, and then charge Democrats with more egregious violations of said crimes, the Left will back off. After all, it’s hard to harass law-abiding citizens from behind bars.
