How Trump’s SCOTUS pick will shift the balance for decades to come

Justice Anthony Kennedy was in the majority of Supreme Court decisions more than any other justice, and according to Axios editor Sam Baker, that's the key to understanding his power. Neither the conservatives nor the liberals could win without him, and his vote greatly impacted major decisions on abortion, unions, affirmative action, and gay marriage.

Why it matters: Trump's pick to replace Kennedy on the Supreme Court could last for decades, and could mean that there may not be many 5-4 decisions that liberals will win.
