It's U.S. presidential debate season again, which means voters will have the rare chance to judge potential presidents side-by-side, without teleprompters, on live TV. The candidates may not always answer questions directly (or at all), and the debates may devolve into platitudes and talking points, but it's still the closest thing to a presidential job interview that most Americans ever get to see.

Environmental issues typically take a back seat in presidential elections, and this year's focus on the economy has so far continued that tradition. But the environment always comes up at some point ? and unlike the rest of the campaign trail, it's harder to dodge tricky issues under the spotlight of a presidential debate.
?
The 2012 presidential race features three debates with three different formats: domestic policy (Oct. 3), town-meeting style (Oct. 11) and foreign policy (Oct. 22). The first two are more likely to address environmental issues, especially those in the current political zeitgeist ? things like offshore oil drilling, natural gas development, carbon dioxide emissions and clean-energy incentives, to name a few.
?
To get a sense for how candidates' environmental priorities have changed over time, I decided to look back at the past 20 years of debate transcripts, courtesy of the U.S. Commission on Presidential Debates. Most presidential elections feature two or three debates, but for simplicity I combined the transcripts into one long document per election. I then made a word cloud for each, revealing the most frequently used words by displaying them in larger text.?
The word clouds can be interesting, but I also wanted to see how much attention was given to environmental issues over time. So, after combining each year's debate transcripts, I searched for a few dozen words and phrases related to environmental policy. I entered terms like "energy," "environment," "climate change" and "offshore drilling," noted how often they appeared in each year's debates, then made a second word cloud of environmental terms for each election season.
