The latest Marist/NBC/Wall Street Journal poll shows Trump dominating Rubio with a double-digit lead in Florida, 43-22 percent. The same poll shows Cruz essentially tied with Rubio, at 21 percent. A separate CBS News 2016 Battleground Tracker poll shows Rubio slipping behind Cruz.

Meanwhile, in Ohio, a Marist survey shows Kasich holding the edge in the Buckeye State with 39 percent to Trump’s 33 percent. The latest Quinnipiac poll shows Trump and Kasich tied in Ohio, with 38 percent each.

The primaries in Ohio and Florida, among five Tuesday, are essentially a must-win for both Kasich and Rubio, respectively – both of whom significantly trail front-runner Trump and Texas Sen. Cruz in the delegate count.

Rubio’s drop in the polls appears to be another indication that his campaign might soon come to an end.

The CBS News 2016 Battleground Tracker poll showed Rubio falling even further.

It showed Trump — who has several, popular golf-resort properties in Florida — maintaining his lead in the state’s winner-take-all primary, in which 99 delegates are at stake.

The billionaire businessman has 44 percent of the vote among registered voters in the state, compared with Cruz at 24 percent and Rubio at 21 percent.
