Betsy Stevenson and Justin Wolfers review some new studies based on what the weather was like on the major launch day of April 15, 2009:
Their research demonstrates that in politics, success begets success. The initial boost from the weather generated substantial momentum. Counties that enjoyed better weather on tax day had more people sign up to become Tea Party organizers, greater donations to an affiliated political action committee, and larger rallies a year later. …
What’s more, the Tea Party experiment shows that the activism catalyzed by those sunny days translates into real political influence. Politicians whose districts were sunny on tax day voted in a more reliably conservative fashion throughout 2009 and 2010. Indeed, the absence of rain in a congressional district on April 15, 2009, made its representative 8.7 percentage points more likely to vote against the Affordable Care Act. Had the weather at those early rallies been sunnier, it’s possible that Obama’s signature legislation wouldn’t have passed.
