The two possibly wavering Republican senators on the committee at Lincoln Chafee of Rhode Island and Chuck Hagel of Nebraska. A pro-U.N. group called Citizens for Global Solutions has been running TV ads in those two states, opposing Bolton's candidacy and urging viewers to call their senators. Chafee is seen as particularly vulnerable, as he's up for re-election in 2006, and Rhode Island is traditionally a blue state. Hagel's press secretary says he will vote "aye" on Bolton. Chafee's spokesman says he's leaning that way but hasn't made up his mind. The foreign relations committee is split, 10 Republicans, eight Democrats. If all the Democrats oppose Bolton, which is likely, Hagel and Chafee—or two unexpected Republicans—would have to join the opposition. If just one of them votes "no," that would result in a 9-9 tie. In that case, a vote would be taken on whether to send the nomination to the Senate floor without endorsement. The dissenting Republican would then have to vote not only against President Bush's wishes but also against giving the president's choice a chance before the full Senate. It's possible, but doubtful, this will happen.
