This is an interesting legal question,
However, I suspect at least one Democrat Senator would realize that such a tactic would so enrage the voters that they would decline to vote for the bill.
Jim Webb: "it would only be fair and prudent that we suspend further votes on health care legislation until Senator-elect Brown is seated."
What does that have to do with legality? It just means Webb is interested in damage control.
Sorry, but, there would only be a legal "controversey" if the Senate were to seek to vote on the so-called Health Care Reform proposal after the election but before seating of Senator-elect Brown.
Therefor, no case or controversey.
