I think Hillary can win the nomination and the general election if SHE spends the next 15 months in a coal mine.
The polls on Colorado and Iowa are not serious.
In Iowa, in 2012, 50% of white voters voted to REELECT Obama.
In Colorado, in 2012, 44% of white voters voted to REELECT Obama. 22% of voters in Colorado were non-white. Almost 80% of them voted to REELECT Obama.
Bottom line....
It doesn't matter who the Democrats nominate.
If they can motivate their core voting groups to go to the polls, the Democrats have enough LEGAL voters to easily win the Electoral College.
Rats don’t have to worry about motivating their core voters. Things with no mass are very easy to move.
