Donald Trump has done his best to convince Americans that his campaign did not collude with Russia in the 2016 campaign, and that Robert Mueller is just conducting an unfair "witch hunt". But most Americans aren't buying his "alternate facts" (lies).
It turns out that 58% think the Trump campaign did have improper contact with Russians during the 2016 campaign. And 61% think Robert Mueller is conducting a fair and impartial investigation. Those are not good numbers for Trump. They show that a majority of Americans are likely to believe Mueller if he finds wrongdoing by Trump (and I believe he will find that).
About 55% also think Trump will not seriously try to stop Russian interference in the 2018 campaign.
