Law enforcement always skews right wing at the basement level, and Comey was a very political pick by a republican president. However Obama erred by keeping him as an olive branch to a party that had no interest whatsoever in compromise or collaboration.
They have, from day one, fought the president by rule, regardless of the policy or subject. They have as a party, abdicated their responsibility to run the country in favor of partisan power juggling, and unfortunately, they have used racism, hatred and falsehood to energize their base and members, and now have a cluster of Tea Party know-nothings, hyper-right wing neo and retro cons and very few "normal" republican politicians, period. It's a mess that they doubled down on at every turn.
The current philosophy is Hate Things and Destroy or Privatize Public Institutions. No other focus.
