Will pork spending cut the other way?

Last May, in the wake of the stimulus vote and Arlen Specter's defection from the GOP, Grover Norquist offered this game-changing observation (bold added):

But what changed, and this is what all Republicans are going to have to learn because it’s new, is that spending became a vote-moving issue. It has not been that before. They don’t call them spending revolts; they call them tax revolts. They take place when the taxes go up, but the taxes never go up in anticipation of spending. Spending usually goes up first.

I don’t think what you learn is whether we should or shouldn’t be primarying this sort of person or that sort of person. What we learn is there’s a new issue—there’s a new issue that can end your political career.

As the 2010 elections get into full swing, we must ask ourselves if this is still true.

I come to this question today through the The Dallas Morning News report on a conservative district held by a Democrat who has historically kept his seat through pork projects.  Can this persist?  The answer, come November, will be fascinating either way.
