The latest Nevada poll finds that Donald Trump is dominating the early state with 45 percent. Jeb Bush, on the other hand, is at a mere 1 percent in the poll.

"The poll finds businessman Donald Trump holding a wide lead, topping the field with the support of 45% of those likely to caucus. Florida Sen. Marco Rubio and Texas Sen. Ted Cruz are closely matched in the race for second place, with Rubio at 19% and Cruz at 17%. Retired neurosurgeon Ben Carson (7%), Ohio Gov. John Kasich (5%) and former Florida Gov. Jeb Bush (1%) lag well behind those three," CNN reports.

"Nearly 6-in-10 likely GOP caucusgoers say they have definitely decided whom to support, with about one-quarter still trying to make up their minds.

"As in the South Carolina poll, Trump dominates the field on handling top issues, including the economy (61% trust Trump most), illegal immigration (58% Trump), ISIS (55% Trump) and foreign policy (42% Trump). He holds a smaller edge over Cruz and Rubio on handling social issues -- 28% say Trump would handle those best, 21% Cruz and 20% Rubio."
