As we wait for results in the Mississippi Senate runoff, it's clear that the race hinges on ideology and turnout.

Interest in the race is high.  In a large-sample survey of 6,381 registered Mississippi voters conducted by HaystaqDNA over the weekend, 67% said that they will definitely vote in the runoff election.   As one would expect, self-reported turnout likelihood is highest among voters who have a declared preference in the runoff, with 90% of Cochran supporters and 94% of McDaniel supporters saying that they will definitely vote.

Voter Ideology

There is a stark ideological divide in the race, with self-identified Tea Party or conservative Republicans being much more likely to support McDaniel.
