Trump's immigration pitch falls flat with Republicans near the border

Republican presidential nominee Donald Trump and Mexico's President Enrique Pena Nieto shake hands at a press conference at the Los Pinos residence in Mexico City

Mexico City: Republican presidential candidate Donald Trump's effort to clarify his position on illegal immigration during visits to both sides of the U.S.-Mexico frontier on Wednesday did little to sway moderate Republicans near the border, a dozen voters in Arizona told Reuters on Thursday.

They were either unaware of his whirlwind tour or found that his uncharacteristically diplomatic demeanor during a visit with Mexican President Enrique Pena Nieto in Mexico City was overshadowed by his return to his usual fiery rhetoric when back on U.S. soil a few hours later.
