Is the military, as a whole, becoming more political than it is professional?

If you are speaking about the political process as in the election, than Yes. If you are talking about inside the military itself...yes as well.

I'm pretty certain that pretty soon here we will have the A-CSM sending out a warning letter to the troops reminding us that we are not allowed to endorse a candidate in uniform, or attend rally's in uniform. Generally speaking service members are not well represented in politics. The right tends to be more vocally supportive than the left, but when it comes down to it both sides will agree to cut something...

CW2 (Join to see) it becomes pretty apparent right around election time doesn't it? You have seen attempts by former JCS to dial it back a bit, but the competition for dollars and resources is an inherently political task. We brief congress on most major initiatives, the COCOMs have direct report roles to the President and serving officers find it hard not to identify with one political party or another. So I would say yes in some very distinct instances.

Just read the average post on this site and it answers your question. Count the number of politically partisan posts vs the number of professional ones. (The answer is yes).
