How can Biden be so far ahead in the polls when very few show up for his rallies ?

The reason why people do not show for his rallies is because of the pandemic. That is why Biden's rallies are virtual. Trump does care if people get infected when they come to his rallies.

This has been understood for decades:  People that hold Left-wing political views are more intelligent!

1 large bill board in the wealthy divorced now married lesbians yard, does not trump the two dozen Trump posters of their neighbors. Polls are misleading to influence. 

Polls can be and are "Special-Ordered".  The DNC and Liberal Media did that in 2016, as well....just ask Hillary.

Only low-IQ gullible simpletons attend political rallies in a pandemic.

Biden wasn't having a rally; it was a closed door event. Trump's lies are ridiculous.

But... rallies are for fascists, not modern world leaders.

True, Biden doesn't look or sound like a pro wrestler. That's because he looks and sound like a president and they look and sound nothing like pro wrestlers.

responding to polls takes zero actual effort....

Biden is not running a death-cult.

He isn't. The polls are rigged to appear that way. Just like in 2016.

Actually, Biden doesn't hold superspreader events the way Trump does.
