Sixty-four percent of Democratic voters surveyed by Democratic firm Public Policy Polling (PPP) support the former secretary of State as the party's nominee for president in 2016, with every other potential candidate trailing by huge margins. Vice President Biden, in second, got only 18 percent support.
But a Clinton run isn't a sure thing, and if she decides against it, Biden's a shoe-in for the nomination, taking 49 percent support to Sen.

Andrew Cuomo takes 10 percent support, and every other candidate is in single digits.
Clinton fares better than Biden against every potential GOP contender tested, leading all of them by margins ranging from four percentage points to seven.

Chris Christie by nine percentage points.
Christie, however, is now in third place among GOP voters in the newest PPP poll.
Rubio maintains his position as the GOP's presidential frontrunner, as he has in every one of PPP's four 2016 polls, holding steady with 21 percent support.
But Paul, buoyed by recent favorable attention surrounding his talking filibuster and straw poll win at the Conservative Political Action Conference, surged in the most recent poll to second place. He now trails Rubio by only four percentage points, up from sixth place with 10 percent support in early February.
Christie comes in slightly behind him with 15 percent support, while Ryan (R-Wis.) and former Florida Gov. Jeb Bush come in fourth at 12 percent. Every other contender received less than 10 percent of the vote.
PPP surveyed 1,247 voters from March 27-30. The poll has a margin of error of plus or minus 3.8 percentage points for the Democratic portion and 2.9 percentage points for the Republican portion.
