Glenn Hubbard describes how the difference in approach between Romney and Obama matters, as it did between Carter and Reagan. The basic difference being the importance of getting long term policy on the right track. See the Reagan memo in Groups for the importance of setting the right tone and emphasis on a consistent long term direction, which was advice given in the memo by Shultz and other advisors to Ronald Reagan. The belief in growth from private sector investment and job creation and putting the right policies in place is a distinct difference between the Romney and Obama plans.
