Story highlights

A Fox News poll shows Ted Cruz with 28% to Donald Trump's 26% in Iowa

It comes after a Saturday poll that put Cruz ahead of Trump by 10 points

(CNN) —  

Another poll shows Ted Cruz leading Donald Trump in Iowa.

A Fox News survey released Sunday shows the Texas senator with 28% support in the first state to vote in the presidential nominating process – ahead of Trump, who is in second place with 26% backing.

Iowa Republicans see Trump as most qualified to handle the economy and Cruz as best qualified on national security, the poll shows.

It comes the day after Cruz was shown with a 10 percentage point lead over Trump in a Des Moines Register/Bloomberg Politics survey conducted by Ann Selzer, whose polls are considered the gold standard in the Hawkeye State.

In the Fox News poll, those two are far ahead of Florida Sen. Marco Rubio, at 13%, and Ben Carson, at 10%.

There’s another gap after that top four to the rest of the pack, with former Florida Gov. Jeb Bush and Kentucky Sen. Rand Paul at 5% and New Jersey Gov. Chris Christie and Carly Fiorina at 2%.

On the Democratic side, Hillary Clinton leads with 50% support – ahead of Vermont Sen. Bernie Sanders’$2 36% and former Maryland Gov. Martin O’Malley’s 5%.
