As Phase Two of the Republican primary plods along, it's worth taking a look at the overall timeline of the 2012 nomination race. July has been relatively inactive, even compared to May and June, several months before many people take interest in the primary. The good news is that early primary polling has picked up significantly this month. This may reflect the fact that the field is mostly settled, and pollsters don't have to worry about candidates dropping out of the race. Or it could reflect an interest in Michele Bachmann's spike in popularity, as most of the new polls come out of Iowa.
At any rate, activity in the 2012 primary has likely reached its lowest point this month. For reasons that will become clear in the timeline below, more will happen in August. In September, Phase Three will begin and campaign activity will gradually increase until someone wins the nomination next year. If the candidates can consider what they're currently doing a vacation, this is it. July will be their last opportunity to breathe.
The following is a timeline of the "structured" events that have occurred and are scheduled to occur until the early primaries begin. It does not include major news events (such as gaffes during interviews).
