Washington Post has the story:
After enlarging their majority in the past two elections, House Republicans have begun to fear that public attention to members' travel and relations with lobbyists will make ethics a potent issue that could cost the party seats in next year's midterm races.Besides DeLay, the other members they're worried about are Bob Ney from Ohio, Richard Pombo from California, and Charles Taylor from North Carolina. But, the whole GOP caucus is tainted by their sleaziness.
In what Republican strategists call "the DeLay effect," questions plaguing House Majority Leader Tom DeLay (R-Tex.) are starting to hurt his fellow party members, who are facing news coverage of their own trips and use of relatives on their campaign payrolls. Liberal interest groups have begun running advertising in districts where Republicans may be in trouble, trying to tie the incumbents to their leaders' troubles.
