The Iowa caucuses are on Monday, and the latest Des Moines Register/Bloomberg poll released Saturday shows Donald Trump topping the GOP field with 28 percent support. Rival Ted Cruz is right on Trump’s heels with 23 percent.

In the previous edition of the poll, released two weeks ago, it was Cruz on top with 25 percent and Trump three percentage points off the lead.
The Des Moines Register/Bloomberg poll has a 4 percent margin of error, so it’s still a neck-and-neck race for Trump and Cruz in the Hawkeye State.
