Many people have very strong political opinions. Their positions seem reasonable and well reasoned to them and they have trouble understanding how any thoughtful person could come up with a different opinion. Even people with less strong views on the issue of whether or not our society is going to come to an end if one or the other party gets into (or continues in power) get hyped up near election time. Its hard not to have a choice in the Super Bowl, even if you are not a football fan.
I have reviewed stamp auction realizations, society membership rolls, magazine subscriptions and the collective memories and wisdom (such as it is) of philatelic old timers and am happy to let you know that you can vote your conscience next month. There is no association between either a Democratic or Republican victory in Presidential elections that seems to have any effect on our hobby. The popularity of philately ebbs and flows but as far as I can make out the rates of taxation on the top 2% or increasing the social safety net have no effect on our hobby. A stamp collecting President, like FDR, made a difference (and with the election so tight maybe one of the candidates will suddenly rediscover their childhood collection) but short of that the things that effect philatelic popularity are things like demographics, the change in entertainment tastes driven by technology and the change in the world wide economy, especially the importance of emerging nations. With all their power, Presidents have little impact on these. So Red or Blue- vote away, secure in knowing that it is only your country, not your hobby, that will be affected.
