This is not surprising. Everyone (even JWs) has an opinion about the news, politics, etc. I know several JWs who are as partisan as any "worldly" person. Of course, whenever they have political discussions, they insert the required disclaimers such as "of course, The Kingdom is the only real hope" and "I look forward to the time when we won't have to worry about this stuff," etc.
I noticed an odd phenomenon over the last couple years during the Obama ascendancy. Lots of JWs (like the rest of the country) were impressed with his soaring oratory and progressive ideas, especially after 8 years of GW Bush. This created cognitive dissonance, and I heard multiple Witnesses talk about how great Obama's speech was...and how that was "scary." The idea was that Obama was so smooth and politically attractive that Satan had to be playing a big role in his success.
Another odd reaction I've seen by some Witnesses is this. They speak in favor of a particular candidate for president--and explain that they hope this person wins because they expect that Armageddon will come during his/her administration.
I see techniques such as those described above simply as ways to get around the JW "neutrality" issue and express a political opinion.
