Most horse-race polls at this point are somewhat useless, but they do contain some interesting internal information:

Independent voters split 44 - 44 percent, the independent Quinnipiac University poll finds. Sen. McCain has a slight 47 - 44 percent edge among men voters and a larger 49 - 42 percent lead among white voters. But black voters back Sen. Obama 94 - 1 percent, while women support him 55 - 36 percent. Obama leads 63 - 31 percent among voters 18 to 34 years old and 48 - 44 percent among voters 35 to 54, while voters over 55 split with 45 percent for McCain and 44 percent for Obama.
