Tom Kean Jr. wants money – and quickly.

The congressman from CD-7 made his appeal for campaign cash by the end of the month deadline in a social media post that began thusly:

“CRITICAL DEADLINE APPROACHING…in a race that WILL decide the fate of our House Majority.”

He’s probably right about that.

CD-7 spanning at least parts of six counties is the most, if not only, competitive House district in New Jersey. Kean won the seat two years ago, ousting Democratic incumbent Tom Malinowski.

He is now being challenged by Democrat Sue Altman.

According to OpenSecrets, a non-profit group that tracks campaign expenditures, Kean had raised about $4.1 million as of June 30 and Altman about $3 million.

However, in this latest appeal, Kean has so-called dark money in mind. These are campaign expenditures on behalf of a candidate by outside organizations. They are a product of the Supreme Court’s much discussed Citizens United decision back in 2010.

“My radical opponent is backed by loads of dark money cash,” Kean says in his appeal, without elaboration.

He adds that his opponents are “trying to buy this seat and push their extreme agenda in Congress.”

Kean, whose social media orations are meaningful because he does not normally hold events open to the press and public, adds that he has something special on his side:

“You.”

He then urges supporters to contribute to his campaign and help protect the Republican majority in the House.
