This hypothesis appears tenable in the current context for several reasons.
For 50 years, the primary structures of lignins have been thought to be random, but for a number of reasons such an assumption is not tenable.
It may sound fanciful to most Democrats, but thus far it's proven to be a pretty tenable position politically, and there's really no pressing reason for Republicans to abandon it.
