Why the Republican Party should pray for rain this November

Conventional wisdom suggests that bad weather benefits the Republican Party because it lowers turnout in general, but particularly among the Democrats. In new research, Yusaku Horiuchi and Woo Chang Kang argue that the difference in turnout caused by rain is not enough to explain the GOP's advantage. They find that poor weather actually makes it more likely that people will vote for a Republican over a Democrat: on rainy Election Days at least 1 percent of voting age adults changed their votes from a Democratic presidential candidate to the Republican.
