I could list other gloomy figures for Obama, but they all leave me with one question: So why is Obama still ahead in the polls? And not just in national polls, but also in key states that are needed for an Electoral College victory.

Shouldn’t Romney be wiping the floor with Obama? By the measurements Romney uses again and again in his speeches — prolonged high unemployment, a failed economy and the unpopularity of “Obamacare” — shouldn’t Americans be rallying around Romney by a significant majority by now?

After all, how long can Romney wait to catch fire? The election is only about three months away. True, Romney gets the opportunity to make a stirring convention speech — but so does Obama. True, Romney gets the opportunity to make an invigorating choice for his running mate, but Obama has already selected Joe Biden, who has shown himself to be a vigorous and popular campaigner.
