In the party’s first major television foray into the competitive June 25 Massachusetts Senate special election, the Democratic Senatorial Campaign Committee and Senate Majority PAC released ads Friday in an effort to define Gabriel Gomez as an ordinary Republican.

That’s the ultimate goal for the party in this Democratic-leaning state. And the two ads released Friday by the national Democratic groups specifically target seniors — potential high-propensity voters even in odd-timed elections. Neither ad mentions Rep. Edward J. Markey, the Democratic nominee, preferring instead to accuse Gomez of supporting cutting Medicare and raising the retirement age.

According to a Republican source tracking ad buys, the DSCC has purchased $751,000 in TV time through June 25 and Senate Majority PAC $448,000 through June 17.
