>> Congressman Taylor sides with Washington special interests.>> It's that time again. Political attack ads are blanketing the airwaves. And they're offering important clues on the state of play just weeks from the 2018 elections. I'm Andy Sullivan in Washington where strategists say television is still the best way to reach the largest number of voters, even in the age of social media.
That makes these TV ads a good indicator of which way the wind is blowing. Clearly showing that Republicans are on defense and the battlefield is expanding in favor of the Democrats.>> Pureval's lobbying firm a made millions.>> In the battle for the House of Representatives, political groups are running twice as many ads they did in the last mid-term election in 2014.
That's according to the Wesleyan Media Project. Republican groups like the Congressional Leadership Fund are placing ads in usually safe GOP territory, where they now look vulnerable.>> Congressional Leadership Fund is responsible for the content of this advertising.>>
>> They're not selling their accomplishments, like cutting taxes or supporting President Trump.
Instead they're digging into the backgrounds of Democratic challengers. This ad argues that Democrat Sharice Davids is too critical of police.>> Davids joined forces with radical left wing protesters to vilify law enforcement.>> GOP groups are also spending money to protect long time Republican incumbents like Fred Upton in Michigan and George Holding in North Carolina.
Another sign that more Republican seats are at risk now than just a few months ago. Republicans are scaling back in some cases, taking down TV ads that support incumbent Keith Rothfus in the suburbs of Pittsburgh, recognizing that he's not favored to win reelection. Meanwhile Democrats are expanding their battlefield, the House Majority PAC putting up new ads in places like central Michigan and coastal Virginia.
>> The Washington shell game.>> This ad targets Dave Brat, a Tea Party stalwart who represents suburban Richmond.>> Brad even voted to allow drug companies to charge seniors more for their medicine.>> Democrats are getting money from some unlikely sources to pay for these ads. Investor Seth Klarman giving at least $3 million.
In past elections, he supported Republicans. These ads are another sign that Democrats are currently favored to win control of the House. And if things keep going the way they're going, Republicans are gonna to have to decide whether it makes sense to keep spending money on races where they're clearly losing.
They've got some tough choices ahead.
