Bill and Hillary's blind investment trust. Is it a conflict of interest?

"Seeking Alpha, 6/18/07, Yahoo Financials" reveals that the Clintons' blind trust just sold Exxon Mobil and British Petroleum. BIG OIL! How long have they held these stocks and how is this any different from blind trusts presumably held by Bush and Cheney? Presumably none of these people know what is held in their blind trusts, and surely the Clintons' trustee will buy other stocks to replace XOM and BP.
