The thing to keep in mind continually is the deception. What deception was being furthered by the misrepresentation of intentions? The deception was to give cover to so-called conservatives and Establishment types for voting for Biden instead of Trump. If it wasn't Biden, then who? Sanders?
No GOP-type could ever vote for Sanders and retain even the slightest credibility. That was the con job.
With Biden as nominee, a "disaffected" GOP-type could still maintain, or try to maintain, bonfides as a faithful member of the conservative side.
The question is whether or not this is working. Who believes this con-job? Do these "RINOS" have any credibility left anyway?
Biden is their fig-leaf. They can always blame the leftism on him, and escape it for themselves.
