That's a pretty _horrible_ example of the parties coalescing into a single viewpoint, since intentionally defaulting on our debts is an extremist view by any definition. That's like saying "clearly the two parties are basically the same because they both don't support nuking Russia". "Both parties agree not to act like lunatics" is a terrible example of "the parties are merging".
A much less bizarre example would be the way the parties have moved towards each other on issues like national security, the finance industry, etc.
