Obama-McCain Dead Heat in Ohio

Ohio is shaping up to be, as usual, extraordinarily competitive in this year's Presidential election, according to a Survey USA poll released today that has Barack Obama leading John McCain 48-42 percent. But since the margin of error is +/- 4.2 percentage points, the two candidates are statistical tied.

Obama and McCain's support is mirrored among opposite demographic groups. For example, McCain leads 58-35 among men, and Obama has the majority of support from women, 59-35 percent. An age breakdown has Obama ahead 52-41 percent among voters under 50, and McCain beats Obama 51-41 in those over 50. McCain wins conservatives 83-13, while Obama leads among liberals 84-15 (Obama also has a 55-36 lead with moderates).

There are a few demographic areas where this pattern doesn't quite hold; McCain peels off significantly more Democrats than Obama wins Republicans (20 percent and 13 percent, respectively), but Obama makes up this gap among independents, among whom he enjoys a 45-39 edge, though a large 16 percent are undecided.
