TalkLeft misfires:

Let’s review exactly what Ifill asked:

IFILL: Governor, you mentioned a moment ago the constitution might give the vice president more power than it has in the past. Do you believe as Vice President Cheney does, that the Executive Branch does not hold complete sway over the office of the vice presidency, that it it is also a member of the Legislative Branch?

I submit that of the 3 people on the stage that night, Palin was the one who got it right on that question. Ifill had no idea what the issue was about and Biden was the one who got it just plain wrong. It is ridiculous that the Left and the Left allies in the Media tried to use this episode to attack Palin. For it was the Media and the Democratic candidate who embarrassed themselves in this episode, not Sarah Palin.

That is just crazy. Palin’s response indicated that the Vice President’s role was "flexible." Biden correctly noted that the VP’s role is actually the most inflexible of any member of the Federal government: the VP breaks ties in the Senate and nothing else. Palin recommended expanding the powers of the office, a curious and dangerous idea which presupposes the VP has powers, which is entirely false.

The Twelth Amendment, it should be noted, does not expand or subtract from the VP’s powers. It simply changes the mode of election.

As for this "legislative role" of the VP, Federalist No. 68 makes quite clear that the tie-breaking role is not legislative, but rather the President effectively entering a veto to definitively resolve the issue:

The appointment of an extraordinary person, as Vice-President, has been objected to as superfluous, if not mischievous. It has been alleged, that it would have been preferable to have authorized the Senate to elect out of their own body an officer answering that description. But two considerations seem to justify the ideas of the convention in this respect. One is, that to secure at all times the possibility of a definite resolution of the body, it is necessary that the President should have only a casting vote. And to take the senator of any State from his seat as senator, to place him in that of President of the Senate, would be to exchange, in regard to the State from which he came, a constant for a contingent vote. The other consideration is, that as the Vice-President may occasionally become a substitute for the President, in the supreme executive magistracy, all the reasons which recommend the mode of election prescribed for the one, apply with great if not with equal force to the manner of appointing the other. It is remarkable that in this, as in most other instances, the objection which is made would lie against the constitution of this State. We have a Lieutenant-Governor, chosen by the people at large, who presides in the Senate, and is the constitutional substitute for the Governor, in casualties similar to those which would authorize the Vice-President to exercise the authorities and discharge the duties of the President.

Emphasis added.

Again: Palin suggested the VP had powers which were "flexible" and should be expanded, without any details. The VP has a single function, with no flexibility, which begs the question of what, exactly, Palin wants to expand. Upon which she refused to elaborate.

Biden correctly corrected her on that.
