Given the circumstances, this should be a golden age of liberalism. Yet the percentage of Americans who call themselves liberals is either flat or in decline. There are now two conservatives in this country for every liberal. Over the past 40 years, liberalism has been astonishingly incapable at expanding its market share…

You would think that liberals would have a special incentive to root out rent-seeking. Yet this has not been a major priority. There is no Steve Jobs figure in American liberalism insisting that the designers keep government simple, elegant and user-friendly. Sailors scrub their ships. Farmers clear weeds. Democrats have not spent a lot of time scraping carbuncles off the state.

Worse, in an attempt to match Republican rhetoric, Democratic politicians are perpetually soiling the name of government for the sake of short-term gain. How many times have you heard Democrats from Carter to Obama running against Washington, accusing it of being insular, shortsighted, corrupt and petty? If the surgeon himself thinks his tools are rancid, why shouldn’t you?…

Liberalism has not expanded because it has not had a Martin Luther, a leader committed to stripping away the corruptions, complexities and indulgences that have grown up over the years.

If you’ll forgive some outside advice, President Obama might consider running for re-election as Luther.
