1. All prosecution is selective. You obviously know nothing about law enforcement. No one said anything about blackmail. If you investigate and prosecute, the goal is not to change someone’s vote; it’s to send him to prison. A few prosecutions, however, would have a salutary effect on the behavior of the other crooks in Congress. At present, on the D side especially, they think laws don’t apply to them, which encourages them to be lawless in every area. 2. A Senator who has no influence over appointments (try to think beyond the cabinet level) does lose donors. Every administration makes 10s of thousands of appointments, most to positions either no one has heard of or knows much about, but they are always important to certain interests. From a donor standpoint, the only thing worse for a member of Congress than zero influence on government personnel is being unable to get pork. 3. As for the media narrative, Limbaugh disagrees with you, and I think he knows just a bit more about the media than you do. Moreover, if you read more widely you would see MSM articles by leftists furious about how much free coverage Trump is getting. Further, if Trump were elected, it would be with a wide base of support, and, unlike your gelded GOPe Presidents, he probably wouldn’t shrink from threatening to “primary” Senators like McConnell if a Senator is doing what they are doing today. What we have forming on FR now is the usual election year circular firing squad.
No, I know nothing about law enforcement, despite having multiple cops, lawyers and other law enforcement professionals in my family. [/sarcasm] The point is that you are advocating selective prosecution based on a person's company's association with a political opponent for the primary purpose of putting political pressure on the opposition. As I said, sounds a lot like the mob or Obama: "That's a nice company your brother has; it'd be a shame if something happened to it..." That is an abuse of power and corruption on a grand scale, and the fact that you can't see that and continue to advocate for such actions should concern everyone.
If you are going to prosecute violations of the law because they are violations of the law, well and good. But if you are going to target specific people because they oppose you or because they give money to your opponents, that is political corruption, and no amount of rationalization on your part can change that.
As for the media narrative, Limbaugh disagrees with you,
Is that supposed to end the discussion? I have a great deal of respect for Rush, but he is not always right. So he and I will disagree on this one.
