On the Jan 31 Poll Texas Pollster: Clinton Latino advantage dropped from 70-7 to 60-29 Dec/Jan
Clinton 48% (46%)
Obama 38% (28%)
Gravel 3% (0%)
Undecided 10% (8%)
Much of Obama's increase has come from his increase in support among Latinos. In December, Clinton had a 70 to 7 lead in this group. The January 10 poll was 63-18. In this poll, the margin was down to 60-29. That is still a wide margin, but 2-1 is a lot different from 10-1
There is a significant gender gap as Latino men under 60 were more likely to support Obama while Latinas under 60 gave Clinton large margins. Clinton easily led both sides of the 60+ group.
Obama's support among African-Americans actually dipped slightly as the number of undecided women increased. Obama still has a large lead 55-21, with 24% undecided.
Both candidates gained among white voters with Edwards departure. Obama gained eight points while Clinton gained five. I can't distinguish between former Edwards voters and prior movement, but my best guess would be that it was a combination of the two. Undecided was also up two points.
Clinton's support was even between men and women, but Obama had seven points higher support among men. Women were seven points more likely to be undecided.
