04 million residents have voted -- including by mail and in person. Political science experts said the campaigns for major races are keeping a close eye on early voting numbers. "The campaigns know who's cast the ballot and who hasn't cast the ballot," said Rice University Political Science Professor Mark Jones.



"Since they have databases where they can predict how people vote -- more or less -- they'll know if they're doing good or if they're not doing as well as they hoped." Jones said it also allows campaigns to target their resources better, reaching out to people who have not turned out to vote rather than people who have.
