@oralloy,
No...
1. The word "objective" means that its truth has nothing to do with your political idedology. In other words it is as true to progressives as it is to conservatives.
2. The word "fact" means that it is testable and falsifiable.
If this were a fact, there would be a set of criteria that defined what "considerable achivement" meant, that we could look for. Of course, anyone liberal or conservative who met this criteria would be considered the same. And if this were a fact, you would be able to define a falsifiability condition. In other words, you would say "if you show me specific evidence that Rush was or did _______ then you will have disproven my 'fact'"
3. This is a bad habit of yours. You state opinions as if they were facts.
