If Republicans can unite, not bad, not bad at all.

Undeniably, Democrats open with a strong hand.

There is that famed "blue wall," those 18 states and D.C. with a combined 242 electoral votes, just 28 shy of victory, that have gone Democratic in every presidential election since 1988.

The wall contains all of New England save New Hampshire; the Acela corridor (New York, New Jersey, Pennsylvania, Delaware and Maryland); plus Michigan, Minnesota, Illinois and Wisconsin in the Middle West; and the Pacific coast of California, Oregon, Washington — and Hawaii.

Changing demography, too, favors the Democrats.
