Why Power in Congress Is So Precarious

“Control of Congress has become so precariously balanced between the two parties that it may now be subject to the butterfly effect,” CNN reports.

“The butterfly effect is a mathematical concept, often applied to weather forecasting, that posits even seemingly tiny changes – like a butterfly flapping its wings – can trigger a chain of events that produces huge impacts.”

“Because it has become so difficult for either party to amass anything other than very narrow majorities in the House and Senate, the exercise of power in both chambers now appears equally vulnerable to seemingly miniscule shifts in the political landscape.”
