I agree 100% that the immigration issue could very well cost biden the election. Biden failed miserably.

Mexican President Andrés Manuel López Obrador blamed President Biden for the migrant surge that has erupted into a full-blown border crisis, arguing the “expectations” he set left migrants with the perception that they would be let in the US.
The Biden administration’s undoing of Trump’s border policies has prompted a flood of Central American and Mexican illegal migrants at the US border, including thousands of unescorted children.
Central Americans looking for refuge from the Northern Triangle countries — El Salvador, Honduras and Guatemala — have taken these policy moves, as well as the overwhelmingly more welcoming tone from Democrats, as a sign that this president is inviting them to cross the border.
