Hispanics of all ages in the U.S. are more than twice as likely to identify with or lean toward the Democratic Party rather than Republican, a new poll says.

But the results of the almost-six-month Gallup survey, released Monday, shows that younger Hispanics are trending toward the Republican Party and independent status at a higher clip than their parents and grandparents, whose loyalties are more rooted with Democrats.

Half of all Hispanics ages 18 to 29 surveyed say they're Democrats or lean toward the party, while 24 percent identify with, or lean toward, the GOP, the poll says.

For Hispanics 65 and older, 59 percent say they're Democrats or lean toward the party, while only 21 percent express Republican loyalties or leanings. Twelve percent say they're independent.

Yet when it comes to President Obama, 72 percent of Hispanics 18 to 29 approve of his job performance, compared with 62 percent of those 65 and older who give the president a thumbs up. Sixty-nine percent of ages 30-49 approve of the way Obama is handling things, while 70 percent ages 50 to 64 say the president is doing a good job.

The struggle for both parties to attack Hispanic voters likely will intensify in subsequent years, as Census Bureau data show that 33.2 percent of Hispanics living in the U.S. are under the age of 18, compared with 19.7 percent of non-Hispanic whites, Gallup reports.

The data was based on survey of 7,901 Hispanics interviewed in English or Spanish between Jan. 3 and June 27.
