A little over a year from now, millions of Californians will be mailed their ballots on the same day that Iowans head to their famous first-in-the-nation presidential caucuses. They could start mailing them back before New Hampshire holds its first-in-the-nation primary in 2020.
Meanwhile, Texans will likely have a chance to vote early, too — even before Nevada and South Carolina, which typically round out the earliest portion of the primary calendar.
The explosion of early voting and reshuffling of the primary calendar in 2020 could transform the Democratic presidential nominating contest, potentially diminishing the power of the traditional, tiny and homogeneous early states in favor of much larger and more diverse battlegrounds. CONT.
