Today I had a sort of revelation. Remember how Cain has always supported Romney, even going so far as to endorse him in 2008? Furthermore, in 2011, he has attacked Perry and other candidates, yet has defended Romney. This is despite Romney's pro-abortion positions, his anti-gun stance, his favorable comments about global warming, his healthcare plan for Massachusetts (Romneycare, the basis of Obamacare), his pandering for gay rights, and his many other liberal policies and ideologies. None of these deficiencies have dented Cain’s support for Romney at all. But something hit me today, and it was the feeling that Cain's support of Romney was due to fear of his past being unearth because more than other candidates, Romney has the resources to go after him.
However, Romney wouldn’t care if Cain plays nice, as he will destroy anyone that crosses him in the path of the GOP nomination.
No, I don’t have any evidence about this - it just hit me today and I just put it together.
It is certainly very possible. Romney has a very polished style but as you note, he is a brutal political combatant. The guy that Cain threatens the most is Romney, since he shot to 1st place and has remained there for a few weeks now.
