How worried is embattled House Speaker Thomas S. Foley about hanging on to his job in the new Congress? Enough so that the Washington Democrat is looking for some reelection help. He has asked Representative Sam Gejdenson (D-Conn.), a six-termer with close ties to both the leadership and disaffected younger members, to organize some small dinners with Democrats. A Foley spokesman says Gejdenson is not a formal campaign manager--which no candidate for Speaker in modern times has had--but many on the Hill see him in that role. Although as yet Foley has no announced opposition, he could face a challenge when the newly elected House holds organizational meetings in December. The Speaker has received bitter criticism for his handling of the House Bank scandal and for failing to be sufficiently partisan in confronting President Bush and House Republicans.
