State representative Katherine Clark will become the first candidate in the race to succeed Edward J. Markey in Congress to air a television ad when a 30-second spot launches tomorrow morning, a campaign official said.
The campaign created two ads, emailed them to supporters, and asked them to pick one goes on air, according to the official.
Several hundred responded, opting for an ad entitled “Test” that features Clark and her mother discussing pay equity and women’s rights and accusing “Republicans in Congress” of opposing equal pay for equal work and birth control rights.
The ad will begin airing Tuesday morning on cable networks, with the campaign spending $65,000 on the first week of advertising. It plans to put more money behind the ad through the Oct. 15 primary, the official said.
The other ad features footage of Clark’s late grandmother.
Both ads appear designed to increase Clark’s appeal among female voters.
The other Democrats in the race are state Senators Karen Spilka of Ashland and Will Brownsberger of Belmont; Rep. Carl Sciortino of Medford; Middlesex Sheriff Peter J. Koutoujian of Waltham; Martin Long, an Arlington author; and Stoneham resident Paul John Maisano, who works in the construction industry.
The three Republicans running for their party’s nomination are actuary Tom Tierney of Framingham, Harvard nanophysics researcher Mike Stopa of Holliston, and businessman and lawyer Frank J. Addivinola Jr. of Boston.
