TG's Political Wire: Early Vote Shifts Heavily to Democrats In Key States.
In seven states for which returned ballot data was available by party, Democratic ballots made up a larger percentage of what had come back by the 20-day mark (that is, by 20 days before Election Day) than in 2012 (or in 2008 for Florida). In some cases, like Arizona and North Carolina, the shift to the Democrats was substantial.
Sounds to me like the 'silent majority' is speaking loud and clear.
