Post-mortems on Fred Thompson's short presidential run focus on how the actor and former senator ran his campaign. Started late, poorly managed, lack of enthusiasm, etc.

But these analyses miss the more fundamental, and instructive, problem -- his message. Touted as the only "real conservative," a careful look shows that this label was pretty dubious. His ideas were devoid of the vision and leadership that fueled Republican ascendancy a quarter-century ago and badly needed today.

On the social agenda, the difference between Thompson and Mike Huckabee was palpable and significant. Huckabee understands that abortion, like the slavery issue years ago, is not a matter of constitutional nuance. It defines our core moral structure as a people and cannot be legal in a nation that exists "under God."

Thompson's take on abortion: It's an issue for the states, not the federal government.

Polls show that public opinion on abortion is moving in the direction of Huckabee. Americans sense the need for moral leadership and it just wasn't there in Thompson's tepid social conservatism.

On the economic front, it's astonishing that the man running as the "real conservative" rolled out a proposal to save our biggest entitlement program -- Social Security.

When Thompson was making his preliminary moves to announce his candidacy, I got interested. I was impressed that he legitimately, and I thought then courageously, pointed out that no candidate was talking about the massive entitlements crisis facing us.

Entitlements -- Social Security, Medicare and Medicaid -- now account for almost 40 percent of the spending in our federal budget. A new report from the Congressional Budget Office says that at the current rate of expenditures, this could rise to 70 percent by 2030. And there is no plan in place to pay for the enormous growing liabilities of these programs. Moody's, the well-known bond-rating service, recently indicated that the current AAA rating of U.S. Treasury bonds could be downgraded.

I thought Thompson was going to revive the important initiative to transform Social Security from a government tax-and-spend program to a program of ownership -- personal retirement accounts.

But instead he unfurled a proposal that could easily have come from Hillary Rodham Clinton or Barack Obama. No personal accounts. Just the same system with a lousier deal. Make a technical change in the index used to calculate cost-of-living increases each year and thereby reduce the size of the payment that the government is obligated to make. Continued...
