According to a senior House Republican, the GOP caucus is "overwhelmingly unified in opposition" to the pork-packed Iraq Supplemental spending bill.  And Republicans think they are are on solid political ground in objecting to both "General Pelosi's" insistence on micro-managing the war and to the Democrats' attempt to buy $ 21 billion worth of votes to get their caucus to support the withdrawal deadline.  According to the lawmaker, these arguments are "unifying forces for us and divisive for the Democrats."  Even House Republicans who supported the non-binding resolution that opposed the surge in troops now state that they are unable to support any measure that "ties the hands of the troops in this way."
