The Democratic Congressional Campaign Committee (DCCC) today unleashed an online ad against incumbent U.S. Rep. Jon Runyan (R-3).

Titled “The Millionaires," the ad tries to punish Runyan for seeking a tax cut for millionaires at what the DCCC says is the expense of the middle class and seniors.

With 100 days until Election Day, House Republicans and Runyan will vote next week to give people making more than $1 million annually a $130,000 tax break, according to the Tax Policy Center.

Runyan seeks re-election in the face of a challenge from attorney Shelley Adler of Cherry Hill.

The new advertising begins today and is the latest phase in the DCCC’s “Drive for 25” campaign.
