There has been no battle as of yet to be lost senator. A few have already objected your tax cuts and now so am I. We need to taxes for the war effort and most of it is coming from our rebellious allies and to propose their taxes be reduced so soon after they rebel against us is almost the talk of a treasonous rebel looking for reparation.
I also assume the Praetor's "violent" response was a typical response to a proposal that was mad, unsound, ambiguous, unfounded and against our military doctrine while being an act that would ignite a war against the Greek city-states which if you haven't noticed surround Rome wherever she goes.
Therefore, the abandonment of Spain and Greece while we are about to obtain victory in the latter was never a possibility in the first place senator, unless you were conspiring against Rome as she finally inches toward the hour of victory.
