As I said in the other thread, I am not a fan of term limits.... I trust the voters.
HOWEVER, if term limits are going to be instituted to get "fresh blood", then it should be that no member can serve more than two full two-year terms EVER. None of this take a year olff and you can come back on.
I would also say it should apply to current members as well... and should not be grandfathered in. If you will have served two terms at the end of your current term, you are ineligible to stand for election again.
Either do not do it... or do it all the way.
