I credit my colleague Hunter Walker who flagged an early version of this a few days ago.
This is from Google Trends and looks at the scale of searches for "Ted Cruz" and "Wendy Davis" over the last six month. The spikes show the period of their respective filibuster events. When we first looked at it the 'search week' wasn't complete yet. So we didn't have full data. But now we do.
What's notable here is that this measures not press attention but popular interest in the two events. And as you can see there appears to have been much, much more for Davis.
Adding the term 'filibuster' to the names makes the disparity even greater.
Now one argument might be that Davis, for most Americans, came absolutely out of nowhere and thus more people might be searching her name than Cruz who's been something of a known commodity for more than a year. Of course, press attention can also drive searches. So the dynamic can work in that direction too.
But even with all these caveats, it's hard not to conclude that there was a lot more interest in Davis's gambit than Cruz's - a fact I find quite surprising. If anything it's the national news media that's out of sync with popular interest and perception.
