...an unwillingness to accept as much

"The performance of the eurozone countries has got worse not better, but so much political capital has been invested in the monetary union project that there is an unwillingness to accept as much."

(The Guardian.)

Is the clause but so much political capital has been invested in the monetary union project that there is an unwillingness to accept as much a comparative one which states that the effort of investment of political capital in the monetary union project corresponds to the scale of the unwillingness to accept (admit) that the performance of the eurozone countries has got worse not better?
