When you add up the origins of the Steele Dossier, and view it in context of the actions of Peter Strzok, Lisa Page, Andrew McCabe, Bruce Ohr, James Comey, and other partisan actors in the FBI/DOJ, I'm sorry... I just can't have faith in Robert Mueller. Comey even admitted that he hoped to prompt the appointment of a special counsel. The whole investigation was goal-oriented from its inception.
I also trust Devin Nunes. We wouldn't even know about many of these facts without his hard work. I have yet to hear anyone refute the facts he's revealed, only minimize their import. For example, I hear frequently from commentators on the Left that the texts between Strzok and Page don't affect the integrity of the investigation, but no one disputes their authenticity. Thanks to Nunes, I can read the texts for myself, along with many more documents he obtained on behalf of the Intel Committee. Nunes's conclusions can certainly be challenged, but he has never shown himself to be a liar, or a "bad actor."
Everyone knows what happened in 2016. Russia had nothing to do with it. Hillary Clinton thought she had a "blue wall" in the Rust Belt, so she basically skipped campaigning there. She was also the target of a validly predicated criminal investigation. She fainted on camera at a time when her health was being debated. She called half the country "a basket of deplorables." On top of all that, she was a pretty lackluster campaigner, and an overall bad foil to Donald Trump. I have voted for Democrats in every election back to Bill Clinton, and I pulled the lever for Donald Trump in 2016. Russia didn't make me do it. Hillary and the Democrats made me do it.
