Sittenfeld also asks viewers to follow him on Twitter, where’ll he be live-tweeting the Democratic debate, adding that “our leaders have always proven themselves worthy in the battle of ideas.”
The 31-year-old candidate doesn’t mention his background during his first TV ad. According to a Qunnipiac University poll released earlier this month, 86 percent of Ohio voters don’t know enough about Sittenfeld to have an opinion of his candidacy.
Dale Butland, Sittenfeld’s communications director, said that because he’s relatively unknown, “this ad will allow many voters to meet PG for the first time.”
“We want to let Democrats who believe Washington needs fresh faces and new voices know that they will have a choice in the Democratic primary next March,” he added in a statement.
An advisor for Sittenfeld’s campaign earlier this year accused David Pepper, the chairman of the Ohio Democratic Party, of trying to pressure Sittenfeld to get out of the Senate race.
