A few quotes from this morning's Frank Rich:

History was on the march well before Mr. Obama boarded his plane, and his trip was perfectly timed to reap the whirlwind.

He never would have been treated as a president-in-waiting by heads of state or network talking heads if all he offered were charisma, slick rhetoric and stunning visuals. What drew them instead was the raw power Mr. Obama has amassed: the power to start shaping events and the power to move markets, including TV ratings.

This election remains about the present and the future, where Iraq’s $10 billion a month drain on American pocketbooks and military readiness is just one moving part in a matrix of national crises stretching from the gas pump to Pakistan. That’s the high-rolling political casino where Mr. Obama amassed the chips he cashed in last week. The “change” that he can at times wield like a glib marketing gimmick is increasingly becoming a substantive reality — sometimes through Mr. Obama’s instigation, sometimes by luck. Obama-branded change is snowballing, whether it’s change you happen to believe in or not.

“We have one president at a time,” Mr. Obama is careful to say. True, but the sitting president, a lame duck despised by voters and shunned by his own party’s candidates, now has all the gravitas of Mr. Cellophane in “Chicago.” The opening for a successor arrived prematurely, and the vacuum had been waiting to be filled. What was most striking about the Obama speech in Berlin was not anything he said so much as the alternative reality it fostered: many American children have never before seen huge crowds turn out abroad to wave American flags instead of burn them.

And, to finish it off:

The election remains Mr. Obama’s to lose, and he could lose it, whether through unexpected events, his own vanity or a vice-presidential misfire. But what we’ve learned this month is that America, our allies and most likely the next Congress are moving toward Mr. Obama’s post-Iraq vision of the future, whether he reaches the White House or not. That’s some small comfort as we contemplate the strange alternative offered by the Republicans: a candidate so oblivious to our nation’s big challenges ahead that he is doubling down in his campaign against both Mr. Maliki and Mr. Obama to be elected commander in chief of the surge.

The comedy continues for another 100 days.
