Age and voting patterns

A poll conducted by Gallop telephone interviews with 21,082 registered voters, aged 18 and older, conducted on March 7-31, 2008, clearly shows that age is directly realted to voting patterns. The polls suggests that younger voters tend to prefer Obama, the younger presidential candidate whereas older voters tend to prefer older candidate McCain. 57% of those polled between the age 18 and 29 support obama, those aged 30 to 39 support the two candidate equally and voters above taht age range slighlty favor McCain.
In terms of gender (Clinton - McCain, Clinton- Obama) this difference seems to be less. SUggesting that age might play a more important role in voting than gender.
