As politely as I can put it, you are a moron.

First, the idea that some anonymous person stating that Gov. Palin does or does not know something, makes it true is ridiculous at best. Second, you and your kid do not know what you are talking about with regards to the Senate. While the VP does not usually preside over the Senate, they in fact can do so...

The Vice President of the United States is the ex officio President of the Senate and can only vote to break a tie. By convention, however, the Vice President presides over very few Senate debates, attending only on important ceremonial occasions (such as the swearing-in of new senators) or at times when their vote may be needed to break a tie vote. The Constitution authorizes the Senate to elect a President pro tempore (Latin for "president for a time") to preside in the Vice President's absence; the most senior senator of the majority party is customarily chosen to serve in this position. Like the Vice President, the President pro tempore does not normally preside over the Senate, but typically delegates the responsibility of presiding to junior senators of the majority party. Frequently, freshmen senators (newly elected members) are allowed to preside so that they may become accustomed to the rules and procedures of the body.

The presiding officer sits in a chair in the front of the Senate chamber. The powers of the presiding officer of the Senate are far less extensive than those of the Speaker of the House. The presiding officer calls on Senators to speak (by the rules of the Senate, the first Senator who rises is recognized); ruling on points of order (objections by Senators that a rule has been breached, subject to appeal to the whole chamber); and announcing the results of votes.
