Jeter voted for Obama: http://espn.go.com/espn/story/_/id/8399887/getting-answers-derek-jeter

If your allegation is true, one vote out of over 40 million is not going to diminish my respect for Derek Jeter in the least. Not only his accomplishments in baseball but his involvement in charity causes and youth groups makes him a true champion of baseball.

Heres one individual who prefers to put sports before biased politics
