No, there isn't.
There are nine people in a room who read the polls and have a certain understanding of the Constitution, backed up by their respective staffs who read the polls and hopefully strive for an understanding of the Constitution.
What the hell do polls have to do with strict legal definitions?
And your choice of words is condemning! A certain understanding of the Constitution? Certain as in fixed or certain as in it's their own interpretation of what it means or as they wish it to be?
Strive for an understanding as in understanding it as it was meant or striving to bring about a "certain understanding"?
Are these the same nine people who swap on and off the computer to battle wits with one person? Or do they simply whisper "sweet nothings" into the ear of the person typing trying to give the illusion that it's just one person instead of nine? Lengthy silences are telling. All that scrambling for an answer, delayed replies. Quick, somebody jump in and take over and get this guy off of my back! Shift change...see you tomorrow! Shift change...the style, tone and argument changes....so obvious.
Yeah, your "nine people" are following the polls. They're following the polls on how this issue is going and they're simultaneously trying to steer it in a "certain" direction and the polls they're watching show whether or not they're successful.
Don't even bother with the petty "tin foil hat" BS.
