Beer Drinkers Are Split in Pennsylvania

Via Extreme Mortman comes this poll from the Keystone State that shows Sen. Hillary Clinton (D-N.Y.) well ahead of Sen. Barack Obama (D-Ill.) among gun owners, bowlers, and hunters, but only tied among beer drinkers in Tuesday's Democratic Primary.

What explains that? Or any of this?

Zogby, btw, is touting a poll which shows Clinton up 6 points (48 percent vs. 42 percent, with 6 undecided).
