Barack Obama spoke Monday afternoon before a gathering of about 250 people – who were invited by his campaign to the Mississippi Valley Fairgrounds in Davenport. The audience included Obama supporters and undecided voters.

Cynthia Ross-Freidhof, who owns a Davenport restaurant with her husband, told Obama she supports him but her husband is undecided. Obama called Ron Ross at work.

"Hey, Ron? Your wife told me that you might vote for me, but I’ve got to do a little work because you’re concerned about whether I’ve got good plans for small business," Obama said over the phone. "I know it’s in the middle of the lunch hour, so I don’t want to interupt too much, but I’m going to give your wife all the answers."

Cynthia Ross-Freidhof is interested to see if the call will make a difference. "I think the fact that Obama cared enough to call and talk to an individual who is worried about this, that owns a little business…I mean, I saw this with him…he’s genuine," Ross Freidhof said of the Illinois Senator.

Obama, who is making his way to Denver to accept his party’s nomination on Thursday, said that 95 percent of taxpayers would see tax cuts under his plan. John McCain, his Republican opponent, has claimed in ads that Obama would raise taxes on the middle class. Obama says that not true.
