Partisan Gridlock?

Former Senator Bayd claimed that one of the reasons why he decided not to run for re-election was that Washington DC was gridlocked by partisan politics. But how much is this really the case? The Democrats did have a super-majority in Senate and had a majority in House; the Republicans were not in a position to do anything to prevent the Democrats from passing any piece of legislation that they wanted. With the election of Scott Brown in Massachusetts the Democrats have lost their super-majority and are no longer filibuster-proof but they still have a strong enough majority that they can pass pretty much anything they want. In the House, while the Democrats are not in such a powerful position as in the Senate, still have a majority and pass much pretty much what they want there.
What about reconciling bills? Remember that whenever a bill passes the House, it goes to the Senate, the Senate drafts its own bill, it gets voted on, but then the House and Senate bills have to be reconciled with each other in conference. Well, again, there is not much that the Republicans can do insofar as conferences go. They can propose amendments, proposals, etc., but in the end there not much they can do to stop the Democrats when it comes to reconciling the bills because after the bill comes out of conference the Democrats still have the votes (if the Republicans do not filibuster) to pass any legislation they want. An aside, who can't reconcile the House and Senate Health Care bills? It's not the Republicans who are causing problems on that front. The so-called "partisanship" is contained within the Democrats themselves.
So, where is the partisan gridlock located? Yes the Republicans (most at least) are consistently voting "No" to Democrat plans. However, I think there is a difference between voting "No" simply along party lines and voting "No" because one thinks the bill(s) are bad. Consistently the Republicans have disagreed with the current pieces of legislation because they believe that legislation is bad because it goes against what they believe is right for the country. Is being partisan? In a way, but not simply because the Republican party is saying "No" just for the heck of it. Saying "No" for the heck of it would be purely partisan but the Republicans have been giving substantive arguments against Democrat legislation.

So, really, is it really has gridlocked as it is being claimed? I myself am skeptical.
