Widely different backgrounds
Tea party people come from such a wide variety of backgrounds that it is hard to put them wholly in one camp or the other. There are many conservative democrats in the tea party for example. It seems to me that you can't generalize too much about them. Personally, I think the tea party will tear itself apart because there are so many different views within it. The leadership may be together right now but their constituents are all over the map figuratively.
"Beloved let us tolerate one another. For tolerance is of God and everyone that tolerates is born of God and knows God. He that tolerates not, knows not God for God is tolerance." 1 John 4:7,8
