While we are parading around the Constitution, let us consider....Term limits are not present in the Consitution for anyone but the President. In fact, you might bother to read the Federalist Papers since we are all about what the Founder's wanted...Federalist 53 pretty much expressly rejects term limits...the author of that pesky argument was....James Madison -- one of the Founders.
Further, the Supreme Court has ruled that term limits at the state level are unconsitutional (see U.S. Term Limits, Inc. v. Thornton). I simply don't understand the obsession with term limits. The people are best equipped to decide who represents them, and they do so every election. If the same person keeps winning, then so be it.
As for Lobbyists -- I again don't get big problem. And again -- let us refer to the 1st Amendment, which states "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances." The court has upheld that this is a free spech issue. If people want to get together in a common cause and petition the government, they clearly have every right to do that.
You apparently want to trample this constitutional rights because you don't like what they are lobbying for.
If the Tea Party wants to build a party based on the constitution, my suggestion would be to start by reading it.
