Approaching Great Strong Leader?

Remember when Republicans constantly argued Bush's gutter approval ratings meant he was a strong leader that didn't follow polling? Accordingly, applying the same logic, that would also mean President Obama's low approval numbers means he's equally as strong, right?  Well not equally as strong since his numbers are still double Bush's final 3.5 years.  But he's moving in the right direction for Great Strong Leader category.  Alas, Republican logic only applies to Republicans it seems.  Thank God.
