The Democrat strategy is to concentrate their effort and hold 14 states plus the District of Columbia that were won by Obama in 2012. The Democrats go after the states with the largest electoral votes.
Winning these states get the Democrats to the required 270 Electors:
California: 55 Electoral votes (60% for Obama in 2012)
New York: 29 Electoral votes (63% for Obama)
Florida: 29 (50% Obama)
Illinois: 20 (58% Obama)
Pennsylvania: 20 (52% Obama)
Ohio: 18 (51% Obama)
Michigan: 16 (54% Obama)
New Jersey: 14 (58% Obama)
Virginia: 13 (51% Obama)
Washington: 12 (53% Obama)
Massachusetts: 11 (61% Obama)
Maryland: 10 (62% Obama)
Minnesota: 10 (53% Obama)
Wisconsin: 10 (53% Obama)
District of Columbia: 3 (91% Obama)
Total: 270 Electoral votes by 14 winning states & D.C.
Additionally Obama won the electoral votes of: Colorado (9), Connecticut (7), Delaware (3), Hawaii (4),, Iowa (6), Maine (4), Nevada (6), New Hampshire (4), New Mexico (5) Oregon (7), Rhode Island (4), and Vermont (3).
NM once liked to think of itself as “independent” between the parties, but Mrs. Bill will likely be a runaway winner there this year.
