Clinton and Bush, for two

ELIS

Think of Ivy League letters shared by presidents who attended the same Connecticut university.

This clue refers to two U.S. presidents—Bill Clinton and George W. Bush—who both attended Yale University, whose students are nicknamed "Elis" (pronounced "EE-lies"). The answer plays on the idea that "Clinton and Bush" share this common label, so the solution is the shortened term for Yale affiliates. It’s a clever way to tie their education to a concise crossword answer.
