(CNN) - Mississippi Democratic voters were sharply divided among racial lines in Tuesday's primary, exit polls indicate.
But Mississippi white voters overwhelmingly backed the New York senator, supporting her over Obama 72 percent to 21 percent.
According to the Associated Press, only two other primary states were as racially polarized - neighboring Alabama, and Clinton's former home state of Arkansas.
The exit polls also indicated roughly 30 percent of Mississippi Democratic voters said race was an important factor in their vote, and 60 percent of those voters supported Obama.
In Ohio, roughly 1 in 5 voters said race factored into their decision. Roughly 60 percent of those voters picked Clinton over Obama.
