The nation experienced an extended period of economic prosperity during the Clinton presidency. While economy remains strong, his presidency oscillated dramatically from high to low and back again in six Acts. According to historian Gil Troy, Act I in early 1993 was "Bush League" with amateurish distractions. By mid-1993 Clinton had recovered to Act II, passing a balanced budget and the NAFTA trade deal. Act III, 1994, saw the Republicans mobilizing under Newt Gingrich, defeating his healthcare reforms, and taking control of the House of Representatives for the first time in forty years. 1995-1997 saw the comeback in Act IV, with a triumphant reelection landslide. However Act V, the Lewinsky scandal and impeachment made 1998 a lost year. Clinton concluded happily with Act VI by deregulating the banking system in 1999.
