Here is the revised Republican national convention schedule, thanks to Townhall. All of the business will be handled on Tuesday, August 28, between 2 p.m. and 6:40 p.m. The Wednesday and Thursday sessions are entirely in the evening and consist solely of talks and speeches. Also there will be a short film honoring Ron Paul on Wednesday evening, sometime between 7 p.m. and 8 p.m.
The party will be considering changes to the presidential nomination process for 2016. That will be dealt with on Tuesday afternoon, before the roll call for President and Vice-President. Here is a Politico article that summarizes the rule changes. Thanks to Rob Richie for the link.
