An interesting but not surprising admission from Rick Santorum today: his aim is not to win the majority of Republican delegates, but to damage Mitt Romney so much that it will force a brokered convention. It’s a Republican battle to the death for the anti-science creationist fanatic.

The memo, to be distributed today, indicates that the Santorum campaign seems more concerned with arguing that Romney will not win a majority of delegates to the Republican National Convention, rather than making the case for why he will. Indeed, the over-2,000-word memo only addresses the possibility of Santorum reaching a majority in its final paragraph, and only as a throw-away. …

The strategy memo also argues that Romney will have difficulty reaching the 50-percent threshold in a three- or four-person race — an argument that is even more true for Santorum, who lacks the same organization and fundraising capacity as the front-runner.

This is a winning-by-losing strategy — and a hard one to sell to voters and donors.
