CBS News analysis: What drives Republican and Trump voters' belief in widespread voter fraud?

Most Americans don't think there was widespread fraud in 2020, but ever since Joe Biden won, most Republicans say there was. This is connected to the push for further voting restrictions in some states, where making voting easier is seen as giving Democrats an advantage. 

A closer look at why some still endorse the fraud claim and what specifically Republicans claim happened — despite the absence of actual evidence — shows a strong link to partisan politics. Republicans say fraud predominantly took place in cities and communities that vote Democratic, but much less so in the suburban and rural areas where many Republicans live. They also say it stemmed from mail ballots, which former President Trump long railed against, and which favored Democrats in many places. Meanwhile, most say ballots were counted properly in the states Mr. Trump won. Moreover, we see the continuing strong influence of the former president's words, with many saying they believe it because they heard it from him, as well as social media and selected news sources.
