Joseph R. Biden Jr. was inaugurated as President of the United States (POTUS) on January 20, 2021. In his inauguration speech, Biden gave glowing remarks about his goal being to unite America and to “Build Back Better.” But in fact, his main goal seems to have been to reverse everything his predecessor, Donald J. Trump, accomplished during his four years as President. Never mind if a policy was benefiting America, if Trump did it, it had to be reversed. This reversal of Trump’s policies did little to unite and benefit America. Instead, Biden’s policies began alienating the half of Americans who supported Trump for those very policies. By reversing Trump’s beneficial policies, Biden began destroying America, as his presidency began to be failing. Biden’s early actions also set the stage for more failures later in his presidency, so it is important to remember them. On the day Biden was inaugurated, he took over the @POTUS account on Twitter and began tweeting profusely. His tweets promoted his “Build Back Better” policies. But with them being a reversal of Trump’s policies, they were often subtle attacks on Trump and his supporters. This two-volume set reproduces Biden’s tweets for the first year of his presidency. It also includes my comments I posted on Twitter in response to his tweets. Some of my comments were added later and reflect later developments. I have also added an occasional “Extended Comment” to provide further context and commentary to some tweets. This Volume One of this two-volume set records all of Biden’s tweets from January 20, 2021 to the end of July 2021. Volume Two will cover his tweets from the beginning of August 2021 to January 20, 2022.
