** FILE ** In this Sept. 26, 1973, file photo Patrick J. Buchanan testifies before the Senate Watergate Committee in Washington. Newly released Nixon-era records show that Buchanan, a special assistant to Nixon and now a conservative commentator, wrote to Nixon's top aide and the attorney general at the time about Alabama Gov. George Wallace, the longtime civil rights opponent who was challenging McGovern for the Democratic nomination. "From an excellent source in Alabama comes word Governor Wallace is `getting psychotic,' that he has serious marital problems and that he is `not what he used to be,' Buchanan wrote in January 1972.
