U.S. politics has never been kind and genteel. Anyone who believes otherwise is wrong. It's always been a game ruled by its most aggressive players. Roger Stone would know; he'd be the first to admit he's one of them.

The reason why this current political climate feels more brutal than ever is because political rhetoric has effectively harnessed the Internet. From newspapers to television to Twitter, politicians and their operatives are masters at innovating new ways to attack their opponents via new media. Even though most people like to look down upon negative attack ads, research suggests they work. The voters aren't interested in facts ? they're interested in emotion. Campaign negativity satiates that thirst. It's what the people want. Roger Stone on Big Think.
