@Tropical_Willie You’re right that Texas deregulated themselves. But context matters. The country was on a roll with deregulation from both parties. Biden played a significant part pulling the Democratic Party away from their historical pro-regulation position:
“Sensing their political weakness with what would become known as “Reagan Democrats,” moderates such as Biden, Hart and Carter worked to move the party decidedly to the right of where it had been for decades. These efforts represented nothing less than an effort to reimagine the Democratic Party, to abandon the politics of the New Deal and Great Society in favor of privatization efforts to achieve priorities such as health care for all and a smaller federal government.” [emphasis added](source)
It’s certainly arguable that if bipartisan championing the wonders of deregulation had not occurred in previous decades, Texas may not have been able to deregulate their grid. It happened amongst a national pro-deregulation landscape that Biden was instrumental in architecting.
I’d be happy to list many de-regulation bills Biden voted for, if necessary, but I’d rather not waste my time pointing out the obvious. Feel free to do some research on Biden’s record. This stuff actually happened and is well documented.
