From Nicole Gelinas at City Journal:
In [Tuesday’s] presidential debate, GOP nominee Mitt Romney returned again and again to a theme: that the last four years have been grim ones for the American people. It’s a message that might seem like a slam dunk. No one is happy with the economy’s performance during President Obama’s term, and if voters are anxious, it follows that they will blame the president. But the approach carries a risk: it may appear to undecided voters that Romney is being too simplistic, even glib, about the deep economic and financial trauma the nation has experienced, as well as the causes of that pain.
Romney would gain more credibility if he’d stretch out his four years to at least six. Put another way: Romney should stop blaming Obama for everything so that he can place blame on Obama where it really counts.
