(http://www.pbs.org/wnet/need-to-know/files/2010/10/karronculture-badge1.gif)We've been hearing for a decade about problems with voting machines nationwide -- it's an issue that Karr on Culture tackled in May (http://www.pbs.org/wnet/need-to-know/culture/audio-ballot-boxing/714/) and that we address on this week's Need to Know. But progressive blogger Matthew Yglesias (http://yglesias.thinkprogress.org/) says there are at least three other problems with the way we cast our ballots. We cast votes for too many offices (http://yglesias.thinkprogress.org/2010/01/for-less-voting/), he says, which prompts voters to make poorly-informed choices. We vote on a weekday, which depresses turnout (http://www.whytuesday.org/). And our winner-take-all electoral system overemphasizes tiny swings (http://yglesias.thinkprogress.org/2010/03/alternative-voting/) in the national mood. Bottom line: Majority rule isn't as simple as it seems.
