I wonder would it reduce or increase gerrymandered districts ?
Primarily because of the increase in voting age Latinos in the more urban states, the Democrats currently have an electoral college advantage. The next Democrat candidate could get to the required 270 electoral votes by winning only 14 states won by Obama in 2012, plus the District of Columbia.
California: 55 Electoral votes (60% Obama in 2012)
New York: 29 (63% 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 by 14 states & D.C.
Obama also won in 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).
