Is the presidential election so close because Biden has refused to take immigration concerns and BLM violence seriously ?

This election should have been a walkover for Biden and the Democrats . He was faced with a sitting president who has proved  incompetent , dishonest and blatantly abusive of his power .

But instead , Biden is in a neck and neck race for the presidency . 

Do you think ,like I do , that it is because Biden and the Democrats have  arrogantly refused to listen to the legitimate concerns of many Americans about the impact that  mass immigration his having on their lives, and also because of their supine response to the BLM movement's dishonest ,and violent exploitation, of the recent black deaths during arrest .

Had Biden and the Democrats addressed these issues honestly and publicly ,would they have got the landslide they should have ?
