Trump pledged to fire Smith, the special prosecutor looking at his obstruction of justice and leading a violent terrorist insurrection.
You voted for Trump anyhow.
Your "concern" for Biden's corruption does not fit your public pledged behavior and is therefore dismissed as false. Also, be cautious about dismissing credibility while supporting Trump, who lied all the time about everything. Unless, of course, you're willing to admit "Trump has far less credibility than the Democrats, due to his years of public words and actions". Anything else will be dismissed as contrary to your public stated stance and therefore handwaved.
