I know people who work for GAO; and every single one oh them are democrats. That office is a joke. They are liberal partisan hacks? Remember their biased report on Obamacare, which was 100% wrong?
How could they not be Democrats? They hire from a pool of employees in the Washington D. C. area where the population is 90% if not higher Democrat. Their H.R. department is most likely already 90% Democrat with a Democrat bias, and any Republican is not going to feel comfortable working among fellow employees who shun him and refuse to talk to him, and is likely to get the hell out just for self-preservation.
