Why Liveblog Democrats and Republicans?

I love how the Times is liveblogging both the Democrat as well as the Republican races. Of course, being Super Tuesday with 24 states holding their primaries.

Without a central location or event or person, and with such a variety of dates and times and places and candidates, how is liveblogging of any value?

This is yet another example of an issue to bring to my Northern Voice presentation on liveblogging in two weeks.
