Yet, only 44 percent of those under 30 knew that Roe dealt with abortion. Forty-one percent thought it might have to do with the death penalty, the environment, or could not name the subject matter.

How can you support what Roe did without knowing what it was about? If they don't understand the holding in Roe, twenty-somethings will be ill-equipped to argue why attempts to restrict access to abortion by conservative courts and states are unconstitutional.

This is why this poll matters: it uncovered that while people support keeping abortion legal, they don't know much besides that.
