(CNN) - On the same day both presidential candidates are set to address a major Latino group meeting in Washington, a new poll shows Americans are closely divided when it comes to building a fence along the country's border with Mexico.
According to a new survey from CNN and the Opinion Research Corporation, just over half of Americans nationwide favor building the 700-mile long fence, while 47 percent oppose the idea.
The poll, conducted on June 26-29, surveyed 1,026 Americans and carries a margin of error of plus or minus 3 percentage points.
CNN Polling Director Keating Holland notes Republicans and Democrats are sharply divided on the issue along partisan lines.
"The American public is closely divided but the two parties are not," he said. "Fifty-eight percent of Democrats opposed a fence on the Mexican border, while 66 percent of Republicans favor one. Independents mildly favor a fence, by a 55 percent-44 percent margin."
Though the issue of illegal immigration played a prominent role in the Republican presidential primary, it appears to be well overshadowed heading into the general election by the nation's economic woes, the war in Iraq, and other issues. A recent CNN/ORC poll showed American's ranked the issue ninth in importance to their vote this November.
Sens. John McCain and Barack Obama, both of whom are scheduled to speak before the League of Latin American Citizens in Washington Tuesday, both voted to authorize the building of the fence in the Senate last year. It carries a price tag of over $3 billion. (Read more on the candidates' immigration stances)
