Looking up the demographics of these counties, it looks like many (Hidalgo, Hamilton, McHenry, Osceola, Prince William, Kane, Salt Lake, Mecklenburg, Loudoun, Riverside) are fast-growing. Are these counties being filled with types of people who generally vote Democratic, or did Obama have a greater appeal to these communities than Kerry did?

Mahoning and Trumbull in eastern OH have over 100,000 votes and swung towards McCain.

Edit: Trumbull swung to McCain by 1.4%. Mahoning is actually wrong on Dave's map--it's shaded blue on the swing map while it swung (though by only 0.61 pts) to Obama.
