Voting has begun in Vermont, Rhode Island, Texas and Ohio. Here's a look at some of the campaign and political news making headlines on this day of important primaries:
• Zogby International -- First polls of the day give Clinton slight lead in Texas; race tied in Ohio: There will likely be several last-minute polls released this morning. The first two are the Reuters/C-SPAN/Houston Chronicle surveys done by Zogby International. They show: Sen. Hillary Rodham Clinton leading Sen. Barack Obama among Democratic voters in Texas, but by just 47%-44%. In Ohio, the two are tied at 44%. Both surveys were done Saturday-Monday. Reminder: Polls are just snapshots of public opinion. ...USAToday blog ...
