An Unstable Senate

Ron Brownstein: “If Democrats lose their majority this year, it will extend a striking pattern: Since 1980, neither party has controlled the Senate for more than eight consecutive years. That persistent volatility marks a distinct change from most of the 20th century. Given the underlying trends in voting behavior, it’s likely the Senate will continue to experience fragile and fleeting majorities. And that points toward both more partisan conflict and mounting pressure to rewrite Senate rules–like the filibuster–in ways that strengthen the majority.”
