I disagree. They need to show the cost of Obama's policies in human terms. If Obama was a Republican, the media would be running stories every day about poor out of work Americans, people who have been forclosed on, filed bankruptcies, homeless, etc. Notice you never see those stories anymore? Romney and the pacs need to bring those people into voters living rooms, with the overt message, "we can't take four more years of this", and the unspoken message "you could be next". As John in Wisconsin noted above, fear sells.
