WASHINGTON (CBSDC/AP) – Approval ratings for President Barack Obama among Hispanics have declined by 23 percentage points inside of one year’s time.

Hispanics, a primarily Democratic voting bloc, have traditionally supported the Obama. In December of last year, 75 percent said they approved of Obama. This year, however, only 52 percent continued to support him.

While still a majority, the figure represents a large shift in opinion. Gallup researchers said the decline was “the most among major subgroups, and nearly twice the national average.”

“Hispanics’ approval ratings of Obama have shown the most variation of any group’s ratings throughout his presidency,” they added in a release on the poll’s findings. “That means their views of him are less firmly anchored than those of other groups, which may help explain why their opinions of the president soured more than any other group’s in recent months.”

All the same, the Obama is still attempting to address issues of significance for the Hispanic community, including immigration.

Obama is blending an aggressive fundraising schedule for Democrats with a pitch for overhauling the nation’s immigration laws, mixing a powerful issue within his party with the inevitable financial draw of an incumbent president.

The Democratic-controlled Senate passed a comprehensive bipartisan bill earlier this year that included border security and a path to citizenship for millions of immigrants illegally in the United States. But House Republican leaders want to deal with the issue piecemeal and don’t plan to hold any votes during what remains of this year.

It isn’t just Hispanics, however. Gallup noted a decline in approval among every major subgroup in America.

“The decline is apparent among all major subgroups, but tends to be higher among groups that are predisposed to support the president, perhaps because those groups had higher levels of approval at his recent peak last December and thus had more room to decline,” those involved in the study observed. “But if the U.S. economy and other national conditions improve in the future, those same groups are likely to lead a resurgence in Obama’s approval ratings.”

Researchers at Gallup added, “The more substantial drop in Hispanics’ approval of the president may reflect, in part, the more volatile nature of their ratings. But it is also a troubling sign for the Democratic Party, given that Hispanics represent an increasingly important segment of the electorate.”

The poll was conducted throughout the entirety of last month by asking 14,352 Americans about their feelings on Obama.
