Polls this close to election day (tomorrow), when absentee ballots and early voting have already taken place, are notoriously sketchy. However, the PPP Poll (full pdf below) does have all of the head-to-head matchups included, and those can put some of the media hype to rest.
Donald Trump is leading in the overall polled responses, and also would be leading each of the candidates individually in head-to-head contests.

(Via PPP) […] Compared to a month ago Trump’s support is up 15 points and Cruz’s is up 14 points. Kasich’s remained in place, and Rubio has seen his support collapse 9 points. Trump appears to already be building up a lead among early voters – he’s at 46% to 38% for Cruz, 11% for Kasich, and 4% for Rubio. Among those planning to vote on election day Trump gets 43% to 32% for Cruz, 11% for Kasich, and 8% for Rubio.
