McCain was comparatively weak among those same groups in Ohio. But Texas was tougher to him. There he lost values voters -- the top candidate attribute in both states -- by a wide 59-30 percent. And in Texas a substantial 44 percent in preliminary exit poll results classified him as "not conservative enough."
As noted, there were challenges within McCain's broader victory.
In Texas, Huckabee won those who attend church more than once a week, 28 percent of GOP voters, by 27 points, 60-33 percent. Evangelicals, a hefty 60 percent of Texas Republican voters, went 49-42 percent for Huckabee. And Huckabee won "very" conservative voters, a third of the electorate, by 12 points.
But McCain came back with broad leads among "somewhat" conservative and moderate Republicans. He won non-evangelicals by a huge margin, 63-21 percent.
He prevailed among less-frequent churchgoers, and won 82 percent of voters focused on the No. 2 attribute, experience. He also beat Huckabee by more than 2-1, 65-27 percent, among senior citizens, compared to with a dead heat among GOP voters younger than 65, 44-43.
In Ohio McCain did better; he won "very" conservative voters, 51-41 percent.
And McCain came closer to Huckabee than usual among Ohio evangelicals, Huckabee's mainstay, while winning non-evangelicals by nearly 50 points. But as in Texas, a candidate who "shares my values" was the most important attribute in Ohio, and Huckabee won them there, too, albeit by a closer 48-40 percent.
At 19 percent, African-Americans didn't increase their turnout in Texas, and it was well down from their 34 percent share in 1984, when Jesse Jackson ran. In Ohio, though, blacks' 18 percent share was up from 14 percent in 2004; that aided Obama, albeit not enough.
Women increased their turnout in both states -- to 59 percent in Ohio and 57 percent in Texas, up from 52 and 53 percent, respectively, in 2004. And Clinton won white women by more than 2-1 in Ohio, as well as by 60-39 percent in Texas.
The upscale/downscale division among white voters was striking. In both states Obama won college-educated white men, while Clinton won those who don't have degrees. In both states Clinton won college-educated and non-college-educated white women alike, but won less-educated women by broader margins.
As previously there were huge generation gaps.
Clinton again easily won seniors, by 73-26 percent in Ohio and 67-30 percent in Texas, while voters under 30 went for Obama by 16 points in Texas and 26 points in Ohio.
In both states turnout among young voters was up from 2004, by seniors, down.
Seniors accounted for 13 percent of voters in Texas and 14 percent in Ohio, fewer than in most states this year. Interestingly, in Texas Obama came close to Clinton among Latinos under 30, losing them by 7 points, while she swamped him among older Latinos.
Also in both states, Clinton prevailed among mainline Democrats. Obama approximately tied her among independents and Republicans voting in both open Democratic primaries.
The economy was the top issue in Texas and Ohio alike, and most strikingly so in Ohio, where 59 percent of Democrats ranked it as the single most important issue, second only to Michigan in the importance of the economy to Democratic voters this year.
