Romney never stood on his own. He was the anti-Obama for Republicans. Like a girl's looking for a guy to cheat with to get back at her boyfriend, the Republican party said, "Meh. You'll do." He never had any strong qualities, such as extreme faith views, or TEA Party ideologies. He's said he's done seeking public office. As a result, there's no reason for anyone to continue to "Like" him, as he serves no purpose for them.
