Open attacks on President Obama

As President Obama is our presumed nominee for the office of President in the 2012 election and it appears that the convention will be a mere formality confirming that, I am wondering when the rules against using this message board to work for the defeat of the Democratic Party nominee for any political office come into play?

I understand that the rules allow constructive criticism of Democrats and the Party but do wonder if giving President Obama the middle name of "Herbert Hoover" or saying that they'll not donate to his campaign, work on his campaign and even vow not to vote for him qualifies as "constructive". Especially if one agrees that President Obama is our nominee, unless something spectacular happens, for President in the 2012 general election.

Thank you.

That rule has not kicked in, and probably will not for a long while.
