Former Democratic National Committee Chairman Terry McAuliffe is heavily outspending his Republican opponent Ken Cuccinelli on television in the Virginia governor's race, according to an analysis of the ad wars by the Smart Media Group.

There has been $16.6 million in advertising -- broadcast and cable TV as well as radio -- purchased in the race. McAuliffe accounts for almost 45 percent of total spending while Cuccinelli is responsible for less than 21 percent, according to SMG's Kyle Roberts.

While the gap in overall spending between McAuliffe/Democratic groups and Cuccinelli/Republican groups is less broad -- $9.1 million to $7.5 million -- the fact that McAuliffe's campaign is outspending Cuccinelli's by a better than two-to-one margin on advertising has to be concerning for Republicans as the race enters its final month.

Thanks to Roberts, here's a handy-dandy chart detailing advertising spending to this point in the race.
