Trump told objective fact lies.
The Keystone pipeline was not shut down.
The Germans did not abandon renewables; they doubled down.
He once again lied about what happened with oil prices.
There are many more. It becomes tedious documenting Trump's changed positions, wrong takes, and blatant lies.
Harris changed her mind on some issues. In every cases from high minded idealism to level headed realism.
Trump has been all over the map and back and forth on healthcare. Harris went from the ideal of national health insurance to the best possible right now of strengthening the ACA.
Harris changed from wanting to ban fracking to a realistic position, while still aggressively pursuing clean energy... Trump lies to make himself look good.
