Current and recent national polls relative to the 2020 Presidential election are ever-changing.
The polls conducted by the Center for Public Policy at the L. Douglas Wilder School of Government & Public Affairs at Virginia Commonwealth University have consistently shown reasons for this.
The questions relative to issues of education, infrastructure, and the economy, etc. don’t change.
The candidates’ responses, or lack thereof, do.
I have consistently stated that my one-word definition of politics is money.
See how it plays.
