WASHINGTON – Most Americans are concerned at least somewhat by the potential for foreign interference in November's election, and a majority believes that Russia sought in 2016 to influence the outcome of that race, according to a new poll that underscores the anxiety and political divisions heading into the final weeks of the presidential contest.The poll from the University of Chicago Harris School of Public Policy and The Associated Press-NORC Center for Public Affairs Research shows that about three-quarters of Americans are at least somewhat concerned about interference, whether in the form of tampering with voting systems and election results, stealing data from campaigns or influencing the candidates themselves or the way voters.
