Economy and environment were on Staff Sgt. Derek Dion's mind. "Things like gas prices, and look at the environment and what we're going to leave our children."
Spc. Joseph Lindsesdt, who is from Alaska, said he was watching for consistency of the candidates' views. "The steadiness of the candidate, whether they've changed their views, constantly, over time, or with political wind, as I like to put it."
To that end, Lindsesdt's pick is Obama. "The fact that he's followed his views, regardless of what they have been [sic] and whether I've agreed with them or not, sometimes. But he's been steady the entire way."
When asked if he was concerned about criticism that Obama had less political experience than some of the other candidates, the battle-weary soldier replied, "No, I think being a decent leader doesn't have to do anything with experience much."
