Every election season, political signs sprout like dandelions from lawns across America. They also pop up at more than a few businesses. For some, expressing political preferences is a calculated move to attract customers. But it can just as easily turn clients away.

Jeff Reiter, who owns the Blue Plate Lunch Counter & Soda Fountain in Portland, Ore., proudly displays a 2008 Obama campaign sign inside his restaurant and says he has "never tried to hide" his support for the president.

There appears to be no question that President Obama will win the lion's share of Hispanic support. But there are still very big questions to be answered about how many votes such support will translate into.

"What we know is that we don't know," says Ruy Teixeira, a political analyst at the Center for American Progress, a progressive think tank.

"If you're the Obama campaign, there's cause for concern, because at least so far, [Hispanic support] is not translating into encouraging data on the turnout front," he says.
