Watch Scott Walker in Iowa

The Economist: “Mr Walker is almost tailor-made to prevail in the first-in-the-nation Iowa caucuses. A credibly conservative evangelical Christian (he’s over there on the right with Messrs Paul and Cruz), Mr Walker has proved his capacity to vanquish Democrats first by laying low Wisconsin’s public-sector unions in a noisy battle, and then by facing a recall and winning re-election in the face of an organized national campaign to avenge the union defeat. Though he is not exactly an electrifying presence, Mr Walker is a well-tested, articulate, union-slaying, budget-cutting exponent of conservative ideals that could appeal to both the pro-business party establishment and the Christian conservative grassroots. This race could get interesting.”
