Gore to avert environmental catastrophe, George W. Bush to carry on
the family business, John McCain to serve his country and Obama to
heal racial and ideological divisions. Romney just seems like
a rich guy who needs a new challenge, writes Steve Chapman. About
Gingrich's motive, there has never been any doubt: to feed an
insatiable ego that makes him imagine he has a historic, God-given
mission to transform the country.
