For years, young voters have been discounted and labeled as apathetic no shows when it comes to voting. After 2012, the age gap will be ignored at a politician's peril. In 2012, according to exit polls, nationwide voters 18-29 years old comprised 19 percent of the electorate while voters over 65 years comprised 16 percent of the electorate. Most importantly, the voting patterns of the young and the old were mirror images of each other on Barack Obama and Mitt Romney as well as on key Senatorial candidates and ballot measures.
In the presidential race, 60 percent of voters 18-29 years old voted for President Obama while only 44 percent of those over 65 did, creating a 16 percent age gap. In key Senate races the pattern persisted. For example, in Indiana, 18-29-year-olds were nearly 20 percent of the electorate compared to 14 percent for the over 65 group; the young voters supported the Democrat, Joe Donnelly, over Republican Richard Mourdock (infamous for his comment that "god intended" pregnancy from rape) by 53 percent and the older voters by 43, creating a 10 percent age gap. The age gap was even larger in Missouri for incumbent Senator Claire McCaskill (D) against challenger Todd Akin (R) of "legitimate rape" fame. McCaskill had the support of 69 percent of the young voters and only 41 percent of the voters over 65 years for a whopping 28 percent age gap. In Ohio, the voters ages 18-24 were 17 percent of the electorate and voters over 65 were 18 percent. The young voters supported incumbent Senator Sherrod Brown (D) by 64 percent while only 46 percent of the older voters supported Brown, an 18 percent gap. An almost identical pattern existed in Pennsylvania's Senate race, where incumbent Senator Bob Casey (D) defeated challenger Tom Smith (R).
- Maine: 68 percent of voters 18-29 years of age voted for same-sex marriage and only 44 percent of the over 65 were, for a 24 percent age gap.
- Washington: 65 percent of voters 18-29 years of age voted for same-sex marriage and only 39 percent over 65 voters did for a 26 percent age gap.
- Maryland: 70 percent of voters 18-29 years of age voted for same-sex marriage and only 36 percent of over 65 voters did, for a 34 percent gender gap.
- Minnesota: 67 percent of voters 18-29 years of age and only 36 percent of the over 65 group voted no on the state constitutional amendment to only recognize marriages between one man and one woman, making a 31 percent age gap.
The age gaps were massive and indicate a tremendous cultural change being driven by younger voters. In each of the four states, voters under 40 were overwhelmingly in favor of the equal marriage position while those over 40 were not. There were also significant gender gaps in all four states with women voting in favor of marriage equality and men rejecting it.
