IEM Remains Unmoved on Barack Post

You can spot a good market by the way it reacts to news. Barack Obama has spent the past week in Denver, orchestrating the Democratic party convention to maximize news coverage and gee up the faithful. Next week fellow presidential hopeful John McCain will aim to do the same for the Republicans. Opinion polls react by delivering a "convention bounce", but spread betters, and traders on the prediction markets of Intrade and the UNIVERSITY OF IOWA ELECTRONIC MARKETS remain unmoved.
