Not according to his campaign anyway, not when he can get away with it. When Romney says "If you re-elect President Obama, you know what you’re going to get. You're going to get a repeat of the last four years,” either he is predicting another catastrophic global financial system meltdown, or he is asking the electorate to develop amnesia. I strongly suspect it is the latter.
Strip away the bravado and Mitt Romney is essentially a one trick elephant. Leaving aside Romney’s appeal to America’s extreme right on social issues (since he himself would rather not discuss that agenda in public debates), his whole case for asking voters to throw out Barack Obama and install himself as President instead comes down to his assertion that a second Obama term means America settling for another four years like the last four, which hardly anyone thinks of fondly.
