Joe Biden is Democrats' top choice for 2020. But look who topped Republicans' lists in December 2014.

For those who say the midterms just ended and 2020 talk is too early: We hear you. Nevertheless, a CNN/SRSS poll is here, and we must listen.

A Democratic primary poll released Friday puts former Vice President Joe Biden on top of the list of potential Democratic candidates, with a convincing 30 percent of voters supporting him. Sen. Bernie Sanders (I-Vt.) comes behind him with 14 percent, and Rep. Beto O'Rourke (D-Texas) is next in line with 9 percent.

Of course, none of these top candidates have fully committed to running for president. And in December 2014 — a little less than 2 years ahead of 2016's election — that race's winner hadn't announced his candidacy either. In fact, a CNN poll from four years ago predicted we'd see some now-forgotten faces on top of a GOP primary.

That's right, remember Jeb Bush, Chris Christie, and Ben Carson? Since topping this poll, they've most recently gained attention for doing nothing, turning down White House jobs, and purchasing a very expensive table, respectively. Eventual President Trump doesn't even appear on the list, suggesting Democrats' next leader could still be yet to come.

CNN's most recent poll surveyed 1,015 people — 463 of whom were Democrats — from Dec. 6-9 via landline and cell phone, with a 3.8 percent margin of error.
