I am not so sure she has a lock on the Obama coalition.
Those who are illegal or illegal related or getting government freebies of course will vote for her......as well as any others who get government welfare of some sort.

Those not dependent and are capable of evaluating what they want can not be assumed to be a sure thing.

And of course the party purists will vote for who ever or what ever represents their party.

The strategy? Keep them poor....keep them dependent.....keep them procreating.....keep them coming across the border.....and by all means let them vote, entitled or not!
