republican website eh? it is a strong keyword, but remember adding the TLD acts as your "second keyword" in this case unlike .COM which is a generalizing TLD. So what your really saying is RepublicanWebsite.com.
16735 republican searches this month?
You say this a extremely strong keyword? I've seen better. Get in the 100,000 range before you say extremely strong. It's decent, that's all it is. Take my word from experience here.
With this in mind, Republican Website Searches this month are...
228 republican web site
(not bad)
I'm not so sure about the value of the .WS TLD, but since you are using it correctly and it has minor searches to it it's probably worth something, I'll have to do a proper appraisal on it later, but for now I think it's worth more then reg fee.
Probably in the $10-low $XX range.
