Mitt Romney should have one sure thing electoral nuclear weapon to use against Rick Santorum — the fact that Obama would crush Santorum and only Mitt stands a chance. The only problem is that it’s not clear that’s true anymore.
According to the TPM Poll Average, Obama now beats Romney by 5.1 percentage points. Obama beats Santorum by 7.2 percentage points. So Romney is a 2.1 percentage points better opponent. By contrast, Obama beats Gingrich by 16.3 percentage points. Big difference.
With Santorum, there’s just not enough to build an argument on.
