I strongly disagree. Even supposing that you credit Obama's rise totally and completely to his political acumen, her campaign had no strategy to deal with a serious challenger and even when all signs pointed to a long and protracted battle, her campaign still believed it would be over by February 5th.
The fact that they didn't even challenge Obama in 9 out of the past 10 states is proof that her campaign has been poorly run. The win in Wisconsin last night was Obama's closest win since Super Tuesday and it was over 15 points. It wouldn't have taken a whole lot just to hold him to a ten point victory in many of these states and that would have significantly reduced his delegate lead.
And then you have her campaign only recently discovering the rules of the Texas primary which put her at a serious disadvantage.
