The Democratic victory lastTuesday was significant not because of its size-there were only a few key races in a handful of states-but because of its scope. Democrats and progressive causes won in the Northeast, where voters in Maine approved medicaid expansion over the wishes of the Trumpist governor and in New Jersey where Democrat Phil Murphy won the race for governor by 12 points. They won in the South where Ralph Northam beat Ed Gillespie by nine points in the race for governor of Virginia. The Democrats also won in the west where a special election flipped the Washington State Senate Democratic, giving the Democrats solid control of the three west coast states.
