In Indiana, the presidential race could be a photo-finish.

Republican John McCain and Democrat Barack Obama are tied at 47 percent each in a poll released Friday by the Mike Downs Center for Indiana Politics at IPFW. Libertarian candidate Bob Barr has 2 percent support, with 3 percent of respondents undecided and 1 percent supporting other candidates for president.

There's nowhere near that much suspense in the gubernatorial race. The numbers from the Downs Center poll show Republican Gov. Mitch Daniels holding a large lead over Democratic challenger Jill Long Thompson, 55 percent to 38 percent. Four percent of respondents backed Libertarian candidate Andrew Horning. Three percent were undecided.

The poll, conducted for the Downs Center by Survey USA, surveyed 900 respondents between Monday and Thursday this week. Margin of error in the poll is 3.3 percent - slightly less than in many polls - because of the large number of people surveyed.

The Downs Center survey also measured support for two other statewide races - attorney general and superintendent of public instruction.

In the attorney general race, Republican Greg Zoeller has a small lead over Democrat Linda Pence, at 46 percent to 42 percent. Because 10 percent of respondents are undecided and the candidates are separated by barely more than the poll's margin of error, both candidates still have strong chances.

In the race for superintendent of public instruction, Republican Tony Bennett has a similarly thin edge over Democrat Richard Wood for this open seat, at 45 percent to 41 percent. Even more of those surveyed, 14 percent, are undecided about this race.
