But so far, there have not been enough new Democratic votes to erase the Republicans’ expected turnout advantage. It remains to be seen whether turnout among new voters will continue at these rates. The Upshot’s model, Leo, still gives the Republicans a 68 percent chance of taking the Senate. “They are wasting their time on margins that aren’t helpful to them when you consider the big picture,” said Kirsten Kukowski, press secretary for the Republican National Committee.
Republicans have long tried to drive Democratic voters away from the polls. "I don't want everybody to vote," the influential conservative activist Paul Weyrich told a gathering of evangelical leaders in 1980. "As a matter of fact, our leverage in the elections quite candidly goes up as the voting populace goes down." But since the 2010 election, thanks to a conservative advocacy group founded by Weyrich, the GOP's effort to disrupt voting rights has been more widespread and effective than ever.
