kidd the optimist thinks:
Hillary Clinton and the crowd of conspirators (Comey, McCabe, etc) are such BIG targets, that likely point to coordination or knowledge by Obama - that any legal action against them HAS to be positively airtight. This takes time - thus the frustration that conservatives have here and on other boards on the web. It would also be best if it all came out at the same time as a blitz on the MSM and should be timed to have the maximum benefit to the mid-term elections. Thus, there must be no leaks and the Trump administration must employ diversions...the Mueller case is so weak that Sessions can afford to recuse himself, for the purpose of optics.
kidd the pessimist thinks:
Most of the GOP is spineless. The GOPe doesn't want to set a precedent of going after the big fish, because future legal action could be taken on them in retaliation by the democrats and the MSM. Other GOP leaders are looking at how this might affect the election (like what happened after the Clinton impeachment) and prefer to sweep this under the rug...the GOP won the 2016 election anyway, right? Others simply are so naïve that they think that they need to play nice to gain favor with the MSM.
I guess I'm a pessimist. I think the GOP is complicit in these crimes by NOT taking appropriate legal action. Proof? Lois Lerner and Eric Holder were found to be in contempt of Congress and they remain free. Give the masses a few show hearings to placate the conservatives until the elections.
