Travel down any road and you're almost certain to spot some kind of political yard sign. They come in countless sizes and colors, but the one thing they share in common: cost.

She says candidates are often identified with issues, and grass-roots campaigning can often prove just as effective in winning a campaign as spending a lot of money.
