The problem is that there are far more swamp creatures in the federal govt. than just 8 years of Kaptain Kenya. We had eight years of both Bush and Clinton, close as brothers (both admitted this).IMO, one of Trump's biggest mistakes was not getting rid of all the Obama holdovers and anyone that showed any loyalty to Obama, or the Democrats.
Trump had only 4 years to rid of 24 years of collected scumbags.
