Where are the conventions being held? That might make a difference. If you live in southern Iowa and the district 5 convention is being held in Sioux City (largest city in the district), is it worth it to make the drive to vote for Edwards?
True enough. Unfortunately, the Iowa Democratic Party website only gives the date, April 26. Locations are "Across the State."
makes it sound like there are many, which makes it seem as if more people are likely to show up. but if Edwards only needs 8 out of several hundred defections/absentees he is going to lose viability.
