If you think about it GWB is not only the child of a President, but his father's career puts him in two political "bloodlines": Eisenhower -> Nixon -> GHWB -> GWB and Reagan -> GHWB -> GWB. Reagan's impression on G.W. Bush and today's GOP is stronger, but that Eisenhower-Nixon lineage is always in the background, and was very important in shaping the previous Bush Presidency. Perhaps it will also be found to be the stronger influence on this Bush Presidency as well.
