I see no problem with politics as long as everyone is respectful.
@Corrine, politics regardless of country can be discussed by anyone. I find politics best discussed in relation to something else which makes the scope global.
I do agree that I don't want any heated discussions but, I see no problem with constructive discussions.
Related to the topic: My Aunt is a Federal Environmental Biologist and is also being affected by the shutdown, I haven't talked to her today but, she is probably in a similar boat as you Tom. (She is also based out of WA)
In my opinion the Gov't is a little too distracted with non-domestic affairs and needs to reevaluate their plan.
