Most of the nation shifted to the right in Tuesday's vote, but not far enough to secure a win for Mitt Romney.

With individual charts showing the components making up Obama's win, labeled as follows:

Republican Gains Among Whites Yield Few Battleground State Victories
Mr. Obama won despite losing the support of white voters by wide margins. Overall, he lost this group by 19 percentage points, even larger than his 12-point loss in 2008

Women Voters Hold Steady
Mr. Obama maintained his support among women: 55 percent voted for him, about the same percentage as in 2008.

Hispanic Voters Increase Support
President Obama won the Hispanic vote by 44 percentage points, 8 percentage points more than in 2008. Among the swing states, the president made the biggest gains in Colorado, taking 74 percent of the Hispanic vote, up from 61 percent in 2008. In Florida, President Obama’s gains among Hispanic voters helped him take the state. He won 60 percent of the Hispanic vote, up from 57 percent in 2008 and 44 percent for John Kerry in 2004.

Young Voters Turn Out Where it Mattered
Young voters favored President Obama, but less so than in 2008. However, he managed to improve his share of the youth vote in swing states like Ohio, Florida and Virginia where his campaign most actively targeted voters.
