To the two previous posters:
Though I've not read Locke, I believe "life, liberty, and property" was a common theme in his writings, and modified by the 2nd Cont. Congress for inclusion in the Declaration. I don't think anyone's denying that the Constitution has something to say about property rights.
However, I think freakazoid was talking about the requirements, in many Anglo-American colonies, that voters own a certain amount of property. These persisted to varying degrees in the early U.S. Thomas G. West has suggested that, as the property requirement receded, it was replaced by restrictions based on sex and race.
