“There is something happening,” said Barack Obama in concession. What’s happening is that this race just became a giant headache for him. All that talk about Democrats and Republicans coming together was, tonight, overshadowed by whatever wonkery he could throw out: caring for veterans, tax cuts, health care policy, nuclear weapons. He has been forced back onto Hillary’s turf of policy plans. Going forward, this Democratic campaign will be about who will promise to do what exactly for which Democratic constituent groups. And this has always been Obama’s weakest hand. The Florida primary fight on January 29th will be about Medicare purchasing power and cap and trade energy programs. The days of “hope” and “change” may just have come to an end.
