It becomes incredibly hard for the average voter now to distinguish the who/what/how/why of politics in the modern world.
Indeed, particularly when people pretend that the two policies are comparable.
Trump is not the first US politician to put a child in a cage. He did distinguish himself by introducing a policy of putting children in cages for no apparent reason.

"Contrary to Biden’s claim, the Obama administration did use caged enclosures beginning in 2014 to hold families apprehended along the southern border by U.S. authorities.
There is photographic evidence showing the cages in 2014. A former Homeland Security secretary under Obama, Jeh Johnson, has said “we expanded family detention … I freely admit it was controversial.”
The ACLU sued the Obama administration over this practice. “Locking up families and depriving them of their liberty in order to scare others from seeking refuge in the U.S. is inhumane and illegal,” Judy Rabinovitz, the deputy director of the ACLU’s Immigrants’ Rights Project, said at the time.
The Trump administration also has been criticized for holding migrants in border facilities with cages. Biden was drawing a contrast between both administrations, but he erred when he said cages weren’t used under Obama.
However, Biden is on solid ground when he distinguishes Trump’s family separation policy from Obama’s. Under its zero-tolerance policy last year, the Trump administration systematically separated all migrant families apprehended at the border.
The zero-tolerance approach is worlds apart from the Obama- and George W. Bush-era policy of separating children from adults at the border only in limited circumstances, such as when officials suspected human trafficking or another kind of danger to the child or when false claims of parentage were made."
