[Cowboy Bob]

After two terms of Trunp, the percentage of Americans identifying themselves as "Liberal" will drop back to below 17% (probably lower).

Remember, after Reagan, most Liberals stopped calling themselves "Liberals." They were too ashamed. They went with "Independent" or "Progressive."

[Olog-hai]

“Progressive” is an old term that socialists such as Woodrow Wilson et al were fond of. That doesn’t even work anymore; after all, John McCain was openly a “progressive” back in 2008, remember.

“Independent” is a clever canard that has not been scrutinized by the public, that is as yet; cf. Bernie Sanders.
