Mitt Romney christened Obama’s Midwest jobs campaign the “Magical Misery Tour” this morning, and that description’s starting to sound pretty accurate. In Minnesota today, Obama brought the doom and gloom as he scolded congress for the slumping economy, and spouted half-hearted appeals for optimism (“We’ve got so much going for us, that folks [around the world] would gladly trade places with us,” he assured the crowd).

The president also blamed a “string of bad luck” over the past few months – including the Arab Spring, the debt problems in Europe and the Japanese Tsunami – for his failure to boost the economy:

Over the last six months, we’ve had a string of bad luck. There have been some things that we could not control. You had an Arab Spring in the Middle East that promises more democracy and more human rights for people, but also drove up gas prices. Tough for the economy, a lot of uncertainty. And then you had the situation in Europe, where they’re dealing with all sorts of debt challenges. And that washes up on our shores. And then you had a tsunami in Japan, and that broke supply chains and created difficulties for the economy all across the globe. So there were a bunch of things taking place over the past six months that were not in our control.

The biggest problem, according to Obama, is that gridlock and partisanship in congress prevented the government from coping with these challenges.

“What’s been happening over the last six months, and a little bit longer than that if we’re honest with ourselves, is that we have a political culture that doesn’t seem willing to make the tough choices to move America forward,” said Obama, adding that the recent fight over the debt-ceiling “ended up creating more uncertainty and more damage to an economy that was already weak.”

But the more Obama points fingers over the struggling economy, the more it undermines his attempt to look like the “adult in the room.” Voters would probably respect him much more if he simply said the buck stopped with him, and actually presented some viable solutions.
