[A]bout half of Americans, 48%, say they think it is at least somewhat likely that in the next few years, some elected officials will successfully overturn the results of a US election because their party did not win…

In January 2021, shortly after the attack on the US Capitol, 59% of Americans said they had at least some confidence that US elections reflected the will of the people. That included 36% who were very confident that elections were representative of the public’s wishes.

Now, a year and a half later, only 42% have some confidence, and just 16% are very confident.

The biggest shifts over that time have come among Democrats and independents, even as Democrats remain the political group most likely to express confidence in American elections. In early 2021, 90% of Democrats said they were at least somewhat confident that elections reflected the will of the people; now, just 57% are. Among independents, the share who have at least some confidence has fallen from 54% to 38%. Among Republicans, by contrast, confidence has modestly increased but remained low, from 23% confident then to 29% now.
