Contributing sentiments towards policy:

47% : Ms Harris has gained some ground among Hispanic voters, a significant voting bloc in Arizona, but Trump still holds a narrow lead in the state.
36% : In Douglas, Ms Harris spoke to Customs and Border Protection officials and viewed part of a border barrier constructed between 2011 and 2012, during the Obama administration.
35% : However, immigration remains an electoral millstone for Ms Harris' White House run, with polls consistently showing voters trust her far less than Trump on border security and tackling illegal immigration.
26% : The legislation was blocked from advancing through Congress by Republican senators following a lobbying campaign by Trump who said he did not want to give Mr Biden a "win" on the border in an election year.
25% : While Trump has promised to carry out mass deportations and other measures to remove both illegal and legal migrants from the country, Ms Harris has attempted a more delicate juggling act.
22% : On Friday, Trump blamed Ms Harris for the rising trend of irregular migration.
