The current discussion of "going nuclear" by the Senate Republicans isn't unprecedented. The Washington Times
recalls the same vote happening in 1975, by Democrats, to reduce the cloture requirements from 67 to 60 votes. The issues then were the same as now: an obstructionist minority, and some in the majority fearful of the repercussions. Among those worried: Senator Robert Byrd, back before he went nuts. Among those for the change: Pat Leahy and Ted Kennedy. I guess where you stand depends on where you sit.
