There has been a rush of spending on TV ads for the pivotal Georgia U.S. Senate runoff, which is just a shortened four-week campaign.

In that period, some $79 million has been poured in to buy airtime. And spending by groups supporting Democratic incumbent Sen. Raphael Warnock has more than doubled contributions from groups backing Republican challenger Herschel Walker, according to data from the ad-tracking firm AdImpact and analyzed by NPR.

The contest, which will be decided Tuesday, went to a runoff because no candidate got above the 50% threshold in last month’s general election to avoid one. Warnock finished ahead of Walker by nearly a percentage point and missed winning outright by fewer than 22,000 votes. A Libertarian candidate got 2% of the vote.
