As Trump's dementia worsens and he becomes more erratic with his little tantrums, we're going to be treated to the sight of congressional Republicans debasing themselves more and more on television, trying to pretend that his latest grudge is very serious and very important.

Contrary to public perception a huge % of pregnant teenagers in the 1990s were impregnated by adult men. The younger they were, the larger the average age gap between mother and father was. Fixing teen pregnancy was in part a clampdown on statutory rape. That's what conservatives want to reverse.
