The white, rural voters who elevated Donald Trump to the presidency might have been underrepresented by Democratic pollsters in the lead-up to the 2016 election, forcing the party to consider how to change its methodology for the future, per Politico.

• Two big reasons for the miss are poor cell phone service in rural areas and anti-establishment sentiment driving down poll participation.
• Democrats likely have underrepresented these voters for some time, but that went unnoticed until 2016 when rural whites were such a key swing demographic.
• "Shy" Trump voters also played a part, as one Dem pollster told Politico, "There's a small group of people who knew that, at some level, they didn't want their support for Trump to be scrutinized."
