Is a centrist approach in politics capable of fostering innovation, or does it inherently favor the status quo?

Centrism allows both parties to negotiate what is better for both of them. We will always have somebody mad when we make decisions, but it's better for everyone to be heard and have a say in the matter.

Centrists provide nothing to a political discussion besides playing devils advocate

Centrism promotes government stability, and enactment of common-sense, bipartisan legislation into law. Centrism can be compatible with innovation as innovation is not inherently partisan, and stability of the central/national government can facilitate experimentation with innovative ideas at the state, and local levels and in the private sector.
