Keller @ Large: New Ads May Heighten Your Disgust With Presidential Race

BOSTON (CBS) - Two new attack videos released by the Clinton and Trump campaigns give us insight into the candidates, and the task undecided voters face making up their minds this fall.

The Trump video is a 15-second walk down memory lane featuring sound bites from two women who claimed Bill Clinton sexually assaulted them back in the '90s and of a cackling Hillary Clinton, supposedly enabling it all. Pretty ominous, isn't it?

Trump's first response throughout the campaign to criticism of his own treatment of women has been to revisit the old Clinton allegations, and in some ways it's quite effective.

It makes Hillary Clinton look dishonest, a perfect match with what the polls tell us is her biggest political weakness. And it reminds voters of how long the Clintons have been around, a negative for some suffering from Clinton fatigue.

In the Clinton campaign's attack of the day, dredging up decade-old sound of Trump appearing to drool at the prospect of the money he can make off the collapse of the housing market that did in fact occur in 2008. This neatly casts Trump as a heartless vulture capitalist who couldn't care less about the human damage caused by the crash.

The problem with all this mudslinging is the lack of any positive information about either candidate, and it may simply turn off undecided voters already repulsed by the tone of the campaign.

I get it, we're in the early, "define your opponent down" phase of the race. But these ads put the onus on the voter to channel their disgust into an aggressive pursuit of the truth, in the hope that somewhere in there is a reason to actually vote for one or the other.
