For now, outside conservative groups are pouring more resources into the race than liberal groups. YG Action, founded by former Cantor aides, has spent more than $1 million on ads and mailings attacking Tierney on his ties to his brothers-in-law. The group now has a poll showing Tisei surging ahead of Tierney. Those ads are being followed up with two weeks’ worth of ads from the National Republican Congressional Committee, the group formally linked to GOP leadership. Among Democratic super PACs, the House Majority PAC last week canceled a $630,000 buy for advertising that would have gone against Tisei. The Democratic Congressional Campaign Committee has more than $1 million worth of advertising reserved in Boston, but it’s unclear how much of that will go toward helping Tierney or helping its candidates in two House races in New Hampshire.
The Tisei campaign has also become a rallying point for a cluster of wealthy Republican donors who support gay rights and would like to see the party move away from some of its recent harsh rhetoric on the issue.
