Congressional Democrats are trying to make Donald Trump’s sex-talk tape stick in some of their key races around the country, unleashing a wave of attack ads trying to tie Trump’s vulgar comments to their GOP opponents. A new campaign ad set to hit Los Angeles airwaves Thursday links Knight to the Republican presidential nominee’s brag that he can “grab [women] by the pussy.” (The final word is bleeped in the spot.) Then, Knight’s Democratic challenger, Bryan Caforio, tells viewers, “I know these aren’t our values” and vows to stand up to Trump “unlike extremist Congressman Knight.”

That comes on the heels of another ad in a different Southern California district, depicting veteran GOP Rep. Darrell Issa, a Trump supporter and newly named campaign surrogate, grinning ear-to-ear and shaking the nominee’s hand. A Trump voiceover plays in the background: “I did try to (bleep) her; she was married.”

All told, House Democrats and the Democratic Congressional Campaign Committee have sponsored four such ads in the five days since the controversial 2005 “Access Hollywood” video went viral. Senate Democrats are also jumping in on the action, using the video in which Trump boasts about getting away with kissing women and touching their genitals because of his “star” power.
