....is this considered a good thing for adult site owners?
I dont know much about US politics but have seen many people in the past either hint or outright blame the current presidential administration as being the main cause for so many small porn sites shutting down due to those 2257 ID laws and certain merchant banks being pressured into not allowing site owners to use them for business transactions etc.

Anyone think things will change with the new administration or will it not make a difference?

Hard to say for sure, but it certainly can't get any worse...

But where would the Doms get 90% of their Clients from, if not for politicians!

Considering most Politicians are/have acted out most scenes you'll ever come across in any Adult site, the day Adult Sites are banned, is the time to pack the bags and leave Earth!.
