That’s not a huge shift, obviously, but combined with all the data mentioned above, the polls are telling a pretty consistent story: It seems that the developments in the Mueller investigation — the Manafort and Cohen news, in particular — have increased public support for the probe. It’s hard to say whether opinions will stick or change in the coming weeks as the Russia investigation continues, but the more support Mueller has, the riskier it will be for the White House if Trump attempts to get in the way of the investigation, say by firing Sessions. Further developments in the investigation could ultimately worsen Republican congressional candidates’ position in the polls too.
