The Diversifying Electorate—Voting Rates by Race and Hispanic Origin in 2012
This is a fascinating little publication from the US Census Bureau about the rates at which whites and minorities vote. A great reference for future arguments. It has many charts, graphs, and data.

Briefly, rates at which non-Hispanic whites vote is declining below that of black voters, both in the low 60% range, while Hispanic and Asian vote percentages has been rising up into the upper 40% range.
I am always astonished, however, by the large number of eligible voters who don't vote.
In comparison to the election of
2008, about 1.7 million additional
Black voters reported going to the
polls in 2012, as did about 1.4
million additional Hispanics and
about 550,000 additional Asians.5
The number of non-Hispanic White
voters decreased by about 2 million
between 2008 and 2012. Since
1996, this is the only example of
a race group showing a decrease
in net voting from one presidential
election to the next, and it indicates
that the 2012 voting population
expansion came primarily from
minority voters.
