I did the Burnt Orange Report tracking poll for Texas this week. As a bit of a preview of the numbers, here's a chart showing the top candidates by age breakdown. All announced candidates were polled, but only the candidates who got 10% of any age bracket are shown on the chart. Some of these slices are pretty small samples, so don't read too much into any one group, but you can see that generally, Hillary Clinton's support is fairly even across this category, while Barack Obama is strongest with younger voters and John Edwards is strongest among older voters.
