What to Know Donald Trump Jr and Ivanka Trump garner very little support among NYC voters for a mayoral run

More voters back Donald Trump Jr than back Ivanka Trump in next year's race for mayor

Trump Jr said this summer he would be interested in running next year

The Trump family's warm welcome from some voters only goes so far, apparently.

An overwhelming majority of polled New York City voters do not want Donald Trump's two eldest children to run for mayor next year, according to a new Wall Street Journal / NBC 4 New York / Marist Poll.

Some 81 percent of registered voters who participated in the poll oppose an Ivanka Trump mayoral ticket, and 80 percent oppose a run by her brother Donald Trump Jr., according to the poll.

Donald Trump Jr. said in July he would be open to challenging Mayor Bill de Blasio next year. Ivanka Trump has not expressed any interest in running, though many see her as a possible political candidate at some point given her work promoting her father's campaign.

Among registered Republicans, Trump Jr. has 5 percentage points more support than his sister. He also draws more support from independents, and has higher backing from both male and female voters.

The Marist poll released Wednesday put de Blasio's approval rating at a 17-month high and found that 50 percent of registered voters think he should be re-elected.

The telephone survey of adults ages 18 and up, speaking either English or Spanish, was conducted Sept. 27 to Sept. 29. Marist surveyed 1,094 adults, of whom 799 were registered voters. The margin of error was 3.5 percentage points.
