Trump is the source of many of our problems. He established a culture of corruption while in the WH. Look at the many investigations currently underway pertaining to him personally and/or his business practices including 2 impeachments. He alienated us from NATO but Biden is fixing his mess. Proof of this can be found in the efforts of NATO to punish Putin for his invasion of Ukraine. Which brings me to another reason Trump is the source of many of our problems.
Trump kissed the ring of Putin and other dictators while in office and now. He praised Putin as a great leader. Can you imagine someone today praising Hitler as a great leader? But many Republicans do exactly that along with praise Putin.
Trump's presidency saw the burning of our cities due to police brutality which he instigated with his racist rhetoric. Remember when he praised the Nazi's in Charlotte? Don't forget he settled a housing discrimination suit. Lastly, the inhumane treatment of immigrants at the border is unforgivable.
