A view of Madison, Wisconsin.Walter Bibikow/Getty Images Republicans are more and more faltering in college towns. Counties where Democrats used to post modest wins have now become routine blowouts for the party. In recent cycles, the GOP has struggled with suburban and college-educated voters, an issue the party must address. In decades past, an array of US counties that contain some of the country's most prominent college towns were often closely split between Democrats and Republicans, reflective of the more liberal-oriented university centers and more moderate-to-conservative suburbs and exurbs balancing each other out.But as many of these towns and cities have grown in population, combined with the Democratic Party's dominance among college-educated voters and those with advanced degrees, many of these counties have begun to rack up huge margins for Democratic candidates up and down the ballot.
