  • Michael S. Lewis-Beck (a1) and Charles Tien (a2)


Our Proxy Model of presidential election forecasting declared, from data issued six months before the November contest, that Obama would garner 52.7% of the two-party popular vote. [See the model release in our Monkey Cage blog-post (Lewis-Beck and Tien 2012a) on September 18, 2012, and in the October issue of PS (Lewis-Beck and Tien 2012b).] Thus, that forecast called the correct winner, with a point estimate error of only 0.9 percentage points.
