David Frum On Party Factions

And the guy makes a lot of sense:
In 1999-2005, when [Newt] Gingrich was focusing on building a second career for himself as a commentator on domestic and international affairs, Gingrich talked about the environment and school reform and healthcare. As hope dawned in him that he might at last have an open opportunity in 2008, Gingrich put those broad themes away, and has slammed instead at the Kenyan anticolonialist in the White House. Romney leaves the door open to non-supporters; Gingrich seals it tight; Palin of course divides the world into supporters and enemies. But unfortunately, the very things that should make Romney an attractive nominee are the things that will likely doom him. What we are likely to get instead is an attempt to pile leverage upon leverage in a style that would have impressed Samuel Insull: to control a great national party that seeks the votes of tens of millions by speaking to the passions and interests of a core group of some hundreds of thousands.

It’s no way to run a company, it should not be the way to run a party, and for sure it’s a terrible way to run a country.
And herein lay the dichotomy of running for high public office. The Christine O'Donnells of the world may fire up the base, but that extreme candidate/ideology will rarely win the day.
