There is no solid public evidence of collusion between the Trump campaign and the Russians or of improper surveillance by the Obama administration, but the poll underscores the extent to which a partisan lens can affect the way Americans view the same set of facts.

Overall, nearly 4 in 10 Americans think some members of Trump’s campaign helped the Russian government influence the election.

The partisan divide on the question is stark: About 6 in 10 Democrats say Russia tried to sway the election with the help of the Trump campaign, while only about 1 in 10 Republicans say that is the case.

Meanwhile, about one-third of Americans think the Obama administration intentionally spied on Trump and members of his campaign during the 2016 election.

There is a sharp partisan divide here, too: Just over half of Republicans believe there was improper surveillance, while only about 1 in 10 Democrats say that was the case.
