Passage: House minority leaders also hold joint news conferences and consult with their counterparts in the Senateand with the president if their party controls the White House. The overall objectives are to develop a coordinated communications strategy, to share ideas and information, and to present a united front on issues. Minority leaders also make floor speeches and close debate on major issues before the House; they deliver addresses in diverse forums across the country; and they write books or articles that highlight minority party goals and achievements. They must also be prepared "to debate on the floor, ad lib, no notes, on a moment's notice," remarked Minority Leader Michel. In brief, minority leaders are key strategists in developing and promoting the party's agenda and in outlining ways to neutralize the opposition's arguments and proposals.
