Canada vs. Mexico

Let's have a look at the US neighbors:


Scale is based on the average worldwide traffic of mexico in all years.
canada 2.22
mexico 1.00

Canada is more popular than Mexico in Google searches. Both are declining but Canada does so much faster than Mexico. However, looking at their occurrence in Google news, both are increasing and Canada does so again faster than Mexico. The two parts of the Google Trends graph seem contradictory... I guess you could say that the countries are receiving more coverage in the news so that not as many people need to look them up? Hmm, you could just as easily expect that more news coverage would lead to more interest hence more searches. I'm not sure about this one. Any thoughts?
