In the meantime, Democratic Sens. Tom Harkin and Jeanne Shaheen introduced legislation this month to lower the number of votes required to break a filibuster. The body's rules for ending debate haven't been changed since 1975, when that threshold was changed from 67 votes to the 60 votes required today. The bill's introduction was not greeted particularly enthusiastically by Reid, however, who echoed the prevailing sentiment about the likelihood of it passing on Capitol Hill. It still takes 67 votes to change Senate rules, Reid noted. "And that kind of answers the question."
