I am one of your followers and I do receive the notifications. But I rarely look at your articles.
I have I think 48 followers but it is a rare hub that 6 people even look at, let alone comment upon.
Your hubs are highly political, and are pretty consistent. How often does one say "wow" over the same meat loaf dinner? Its not that your readers disagree with you (except me of course) , its just that you are serving up essentially the same flavours every time.
When you started there were many fewer hubbers, but now you have competition on the Right. Some of the competition are more extreme than you, some more intellectual than you, and some more crude than you. The other problem is that because of the recent Republican victories Obama is fettered in what he can do, so the general sense of strident panic on the Right is more muted.
Carry on writing, and build up a body of work of which you can continue to be proud.
Look at your hubs which are most and least successful and see if there is anything to be learned.
If you want comments, write about baseball! It does not matter what you say people will object!
