The pipeline never finished, so there was never a vaccuum to be created by its incompletion. Gasoline is so abundant that people buying a few extra gallons will not increase the demand to a markable difference, or reduce the supply in such a manner. No one is saying Trump controls COVID. What we do say, is that there is causation and correlation between Trump and how he downplayed the virus and the measures used to combat it, and the number of deaths that has occurred.
No, the increased gas prices are the result of a lack of truckers because of the pandemic. In that, the pandemic has put many businesses out of work, some of them being shipping companies. There have also been backlogs of shipping because there are less workers to receive shipments at our importing ports. As such, since our incoming imports are being processed more slowly, our reduced interstate shipping capacity, this creates an increased demand for products because their supply is diminished.
So, you're wrong on both counts. If only the pandemic was handled properly.
Cool poisoning the well fallacy, by the way.
