Democratic Primary Map Illustrates Clinton's Successes and Challenges

Picture a "typical" Bernie Sanders supporter. Before the primaries began in earnest, most people probably pictured a Birkenstock-wearing, Occupy protesting, anti-climate change activist who lives in Seattle, Austin, or Boston. Many still do. However, with the benefit of primary hindsight, we now know this stereotype wasn't fully accurate - and it's why Hillary Clinton still has a lot of work to do to unite Democrats. As it turned out, Sanders's support came from young, low-income whites. But it's where his support was highest that proved a bit surprising: he won a higher share of the vote in working-class manufacturing towns like Wausau, WI (59 percent), Terre Haute, IN (55 percent) and Binghamton, NY (57 percent) than the counties containing Seattle (43 percent), Austin (52 percent) and Boston (42 percent). This week, we compiled county-by-county results from official sources. Overall, Clinton won about 17.3 million votes to Sanders's 13.5 million in primaries and caucuses between February and June - a landslide compared to President Obama's edge in 2008: Credit: Ally Flinn But in an ironic twist, Clinton survived the Sanders surge
