>>1) Anyone who voted R in 2010 is an R regardless of if they voted D in 2008 or 2006
2) Anyone who voted R in 2008 is an R unless they voted D in both 2010 and 2006
3) Anyone who voted R in 2006 is an R unless they voted D in either 2008 or 2010
My queries then should be

Is a person either R or D or is a person R or not R?

I'm bleary-eyed but it seems that if someone voted R in 2010, R in 2006 and D in 2008, that person would be an R under rule 1 but not under rule 3.

Am i correct?
If so which one would take precedence?
