You don't specify the Court system in which your case is pending, so it not possible to give you anything even resembling a definitive answer. I will assume you are litigating in Washington State, since Oregon no longer has District Courts.
In Washington's District Courts, the rules controlling the action are the Civil Rules for Courts of Limited Jurisdiction ("CRCLJ"). Your best procedural choice is probably contained in Rule 12. You have two potential options. First, you can move for a Judgment on the Pleadings under Rule 12(c) if the facts asserted in defense could not lead a reasonable jury to find a valid defense. Second, you could file a Motion to Strike under Rule 12(f), attacking an insufficient pleading and potentially leading the Court to find the defendant in default. Third, you could file a Motion for a More Definite Statement under Rule 12(e) to challenge a vague and uninformative pleading.
In answer to your actual query, you could file a Motion for Summary Judgment under Rule 56. If you have been running the opposing attorney around the ring for two years, why are you only now getting the case at issue and considering SJ? Obviously, there are many facts in play which you have not supplied. Those facts will almost certainly be determinative of your answer.
Nobody can answer the question of whether you will win a summary judgment motion based on the information that you have provided.
There is nothing inherently wrong with a defendant filing an answer that is just a general denial of all the plaintiff's claims, and it certainly doesn't mean that summary judgment is appropriate.
If you want to know whether you can win a summary judgment motion, you should hire a lawyer to evaluate the strengths and weaknesses of your case.
