The 2016 presidential race is arguably already over in 40 states and the District of Columbia. If recent presidential election trends are any indication of what will happen in 2016, Democrats in Texas and Republicans in New York might as well stay home on election day because their votes will matter little in the presidential race. The same might be said for the voters in 38 other states too. Conversely, for those in Ohio, Florida, Colorado, Iowa, and a handful of other states, their votes matter. These states will be battered with a barrage of presidential candidate visits, commercials, political spending, and countless stories about them by the media. Understanding why the presidential race has been effectively reduced to only ten states is the subject of Presidential Swing States: Why Only Ten Matter. Stacey Hunter Hecht and David Schultz offer a first of its kind examination of why some states are swingers in presidential elections, capable of being won by either of the major candidates. Presidential Swing States describes what makes these few states unique and why the presidency is decided by who wins them. With cases studies written by prominent political scientists who are experts on these swing states, Presidential Swing States also explains why some states have been swingers but no longer are, why some are swinging, and what states beyond 2016 may be the future ones that decide the presidency.
