Is utterly shameless.
When Trump was president it was horrible, shocking, racist, hateful, and impeachable that children dangerously and irresponsibly pushed across the border were detained when no actual relative could be found to care for them, that travel was restricted from countries deemed especially likely to introduce more infected people into the US, that the President might step cautiously while walking down a wet metal ramp, that a historically rapid rollout of a vaccine was promoted by the President, that riots and mass shootings took place under the President's watch, when the President used the symbolic power of the office to influence Americans, when he encouraged deficit spending for policies he considered important, and when the President couldn't magically make all trace of the virus disappear.
But NOW..............................
...you do realize that this hypocrisy works both ways? Those that praised Trump's border policy, condemn Biden's? Those that supported Trump's travel ban condemn Biden's? Those that defended Trump's stumbling take every opportunity to show Biden stumbling?
On the other hand, this president has not yet corrupted his power in an attempt to find dirt on a political opponent, nor has he encouraged a mob insurrection to overturn an election or pressured elected officials to "find votes".
It is still horrible to separate families at the borders, it's worse to push children back into Mexico where there are no protections whatsoever. It's Biden's watch now. Let's see what he does.
