Lindsay Graham complained about Biden using the "race card", with respect to the filibuster.

After four years of Trump, who played on racial fears to get elected and continued daily stoking of race resentments, any Trump Republican is the wrong messenger. Doesn't make him wrong, but it does make him someone complicit in racial identity politics for many years. He's not the guy to deliver this message. Better get Mitt.
