Prospect online this week: America (and Glenrothes) decides

While the eyes of the world have been trained on America's bellwether states, Prospect has not forgotten that a "bellwether" by-election is also taking place in Scotland. Jamie Stevenson argues that Cameron's Tories have most to gain from a resurgent SNP; even if this means a successful independence bid in 2010. And Alice Onwordi looks at the party most auspiciously absent from the Scottish fray: the Greens. Although the Greens have grown significantly in the last 5 years, with the combined threats of a resurgent BNP, mainstream parties stealing their policies, and their own hopeless disorganisation, they have a tough battle on their hands to remain Britain's fourth party.

Plus, not wishing to neglect the other election taking place this week, Erik Tarloff will also exclusively report from inside the election night party at Obama HQ in Chicago.
