When Illinois Sen. Barack Obama asked his audience in Vinton who was still undecided, Stephanie Roepke raised her hand. 

But after his speech, she said she had made up her mind and will caucus for Obama on Jan. 3, 2008.

Before the event, she was leaning toward caucusing for Connecticut Sen. Chris Dodd and had made Obama her second choice after taking an on-line quiz to see who most closely matched her ideal candidate. The result from the website was Dodd. 

But after listening to Obama speak, Roepke changed her mind. She said that the Illinois senator has “a much better chance” than Dodd.
