Agreed. 51-49 makes it too inviting for someone to get threatened/bribed and jump to the D side, if not explicitly then implicitly.
Then again, if conservatives can be a strong enough presence in the US Senate, they might win over some dems such as Manich (sp) whose state’s issues have been decimated by Obama. And RINO backstabbers might have to behave better, knowing it’s the conservative message that’s resonating with voters.
