Sarah Palin briefly arrested the collapse of John McCain’s odds of winning the presidency with her performance in the debate last night: By this morning, McCain’s odds on Intrade had upticked from 33% to 33.8%.
Alas, the Palin effect quickly wore off, and by the end of the day, McCain’s odds had plummeted to a new post-convention low: 30%. McCain has now lost 18 points in the past 18 days.
