Poll: "Sharp Reversal" For Obama With Hispanic Voters

John McCain has been courting Hispanic voters heavily. But according to a new Pew Research Center poll, it hasn't done him much good:

Hispanic registered voters support Democrat Barack Obama for president over
Republican John McCain by 66% to 23%, according to a nationwide survey of
Latinos conducted by the Pew Hispanic Center, a project of the Pew Research
Center, from June 9 through July 13, 2008.

The presumptive Democratic nominee's strong showing in this survey represents
a sharp reversal in his fortunes from the primaries, when Obama lost the Latino
vote to Hillary Clinton by a margin of nearly two-to-one, giving rise to
speculation in some quarters that Hispanics were disinclined to vote for a black
candidate.

Obama is rated favorably by 76% of Latino registered voters, making him much
more popular among that voting group than McCain (44% favorable) and
President Bush (27% favorable). He now appears to be even more popular than
Hillary Clinton among Latinos (73% favorable).

George W. Bush took 40% of the Latino vote in 2004, a record for a GOP candidate. According to Pew's results, the long-term Hispanic shift Republicans hoped for hasn't materialized:

In addition to their strong support for Obama, Latino voters have moved sharply
into the Democratic camp in the past two years, reversing a pro-GOP tide that had
been running among Latinos earlier in the decade. Some 65% of Latino registered
voters now say they identify with or lean to the Democratic Party; compared with
just 26% who identify with or lean to the GOP. This 39 percentage point
Democratic Party identification edge is larger than it has been at any time this
decade; as recently as 2006, the partisan gap was just 21 percentage points.
