Forty-one senators from our 21 smallest states — just over 10 percent of our population — can block bills dealing not just with health care but with global warming and hazards that threaten the whole planet. Individual senators now use the filibuster, or the threat of it, as a kind of personal veto, and that power seems to have warped their behavior, encouraging grandstanding and worse.
