WFAA in Dallas will host a debate at 7pm tonight between Republican U.S. Senate Candidates, Ted Cruz and David Dewhurst. Tonight will be the final debate before the July 31st runoff. The race is close and both campaigns accusing each other of lying. Money wise, it's close as well with Ted Cruz raising slightly more than David Dewhurst. Dewhurst did receive more votes in the primary, but many believe Cruz has the momentum right now. You can watch tonight's debate online at at 7pm. Do you plan on watching?
