Stunning number of Trump supporters are more likely to support him if he softens on immigration

Forty-eight percent of Donald Trump supporters say they are more likely to support the Republican presidential nominee if he softens his immigration position, according to a Fox News poll released Wednesday evening.

Only 15% of Trump supporters said they would be less likely to vote for the New York businessman should he soften his views on how to deal with the millions of immigrants in the US illegally.

Thirty-six percent of Trump supporters said it made no difference, and 1% said they were unsure.

The Fox News poll also found that 77% of registered voters were in favor of setting up a system to legalize the immigrants in the US illegally. That number represented a 13% jump from last July, when only 64% of voters said they supported such a system.

Only 19% said in the Wednesday poll that US policy should be to deport as many individuals as possible.

The poll was released just hours before Trump was set to deliver a major speech announcing his immigration positions.
