‘Same Since’ Electoral Maps

States that have voted for the same party in consecutive elections

While the country has become more politically polarized over the past half-century, the number of competitive states took a leap forward in 2016. Michigan, Pennsylvania and Wisconsin voted Republican for the first time in a generation. Several other states, including Arizona, Georgia, Maine (at-large) and Minnesota, kept their long-standing single party streaks intact, but saw a much closer result than in recent elections.
