The Louisiana Democratic Party has launched a web campaign against GOP presidential candidate Donald Trump, with a very specific message attempting to appeal to Louisiana voters who don't like former Ku Klux Klan leader David Duke.

The Democrats' ad ends with "Get involved. It's important." -- a throwback to the pro-Edwin Edwards "Vote for the Crook. It's important" rally cry from the 1991 governor's race. It's clearly meant to appeal to those same types of people who couldn't see themselves supporting Duke in that race.

The ad doesn't mention Democrat Hillary Clinton by name. Instead, it splices together cuts of Trump's February interview with CNN's Jake Tapper in which he repeatedly refused to disavow Duke along with national news clips of Duke during his campaigns for Louisiana governor and president.

The ad opens with Tapper: “Will you unequivocally condemn David Duke and say you don’t want this vote or that of other White Supremacists in this election?”

And Trump's response: “Well just so you understand,I don’t know anything about David Duke.”

From there it repeatedly cuts between footage of Duke and the exchange between Tapper and Trump.

Trump conducted the CNN interview remotely and later said "a very bad earpiece" was to blame for his refusal to condemn Duke. He told NBC's Today that he could "hardly hear what (Tapper) was saying" though he repeated the name "David Duke" in the interview.

Duke is running for U.S. Senate and has repeatedly sought to link himself to Trump, most recently through robocalls urging voters to support the two candidates on election day. 

Meanwhile, Trump has since defiantly rebuked Duke's support and said on Meet the Press, if he were given a choice between a Democrat and Duke, he would back the Democrat.

Trump, who won the Republican primary in Louisiana, has shown a significant lead over Clinton in polls of Louisiana voters. He further drew praise for visiting Louisiana in the wake of catastrophic flood, when he toured some of the hardest-hit areas and met with flood victims.

Clinton has said she plans to visit Louisiana but has not traveled her in the wake of the deadly flood.
