State Rep. Carl Sciortino, a candidate in next month’s 5th District special election in Massachusetts, released his first campaign ad of the primary cycle on Tuesday, marking the second candidate in the five-person field to go up on air.

The 60-second ad will begin airing Wednesday on MSNBC, CNN and Comedy Central, according to the campaign. A campaign aide said they have bought more than $100,000 of airtime but did not disclose an exact dollar amount. The campaign will be on air through the duration of the primary cycle, which ends Oct. 15.

In the ad, Sciortino, who is openly gay, comes out as a “Massachusetts liberal” to his father, a member of the tea party. In a witty back and forth, Sciortino’s father describes the progressive policies Sciortino has worked on during his time in the Massachusetts state House.

“This one drives him crazy,” Sciortino says, to which his father replies, “He wants to go to Congress to take on the NRA and the tea party.”

Sciortino is one of five candidates running to replace Edward J. Markey, who was elected to the Senate in a special election this June. Sciortino and the other four candidates in the race — Middlesex Sheriff Peter Koutoujian and state Sens. William Brownsberger, Katherine Clark and Karen Spilka — have been fighting for attention in this contest as a higher profile mayoral race takes place in neighboring Boston.

So far, Sciortino and Clark are the only two candidates up on air.

Massachusetts’ 5th District is rated a Safe Democratic contest by Rothenberg Political Report/Roll Call.
