Demos to Watch in Pa. Vote

Some of the election season’s most intriguing demographics will be out in force in today’s Pennsylvania primary. The Wall Street Journal breaks down who they are and how they might vote in November.

• Working-class white males mostly went red in 2006, supporting Republicans by a 14-point margin. Increased economic worries could swing some, but will they cross gender or racial lines?

• Young voters love Barack Obama. Their primary turnout has tripled compared to 2004, but they vote less than other demographics and may skip November.
• Rural voters have long been a problem for Democrats, and "Bittergate" won’t help.
• Hispanics have soured on Republicans since 2004, but John McCain is counting on them.
