the "I don't vote party lines" is just as much rhetoric as saying "I vote straight (R) or (D)"
personally, I vote down party lines depending on the issues. However, I do vote (D) for schoolboard stuff, I vote (R) for the rest of it.
It's funny because the person I vote for or against for Superintendant would be opposite if they were running for Mayor.
SO I vote how the party votes on issues.
If it's people who deal with abortion or gay rights, I'll vote Republican down the line
If it's people who deal with education, I'll vote (D)
When it comes to individual referandums, I'll vote the way that best suits me and my family's need.
