Is moving to the center possible in todays politics esp. with an election near?

[TML]

It seems to me that in today's political environment, "moving to the center" is code for endorsing policies which are pro-corporate, pro-establishment, and pro-status quo. If you were to take a more accurate measurement of the general public's political viewpoints (not influenced by the establishment bubble), you will find that the true political "center" is more closely represented by the likes of Bernie Sanders than the likes of Joe Biden.

This is why I do not want the Democratic nominee, whoever he or she turns out to be, to "pivot" to the center/right after winning the nomination, because we all saw how that played out in 2016. Instead, he or she should hold firm on the left, because that is what will increase turnout among Democratic base voters and draw first-time voters to their side (contrary to popular belief, so-called "moderate" voters comprise a smaller slice of the electorate than Democratic base voters and untapped voters).
