GOP Iowa debate-tensions mount as candidates feel the field may be thinning

Republicans took the stage Sunday (early Sunday morning) in the first network television debate and it started with some taking shots at the republican candidate leading the polls, Mitt Romney.
Senator Brownback has an ad attacking Romney on his changing stance on abortion. Brownback considers abortion a core issue of the Republican party, and later vowed to nominate a supreme court justice that would overturn Roe Vs. Wade. Romney seemed to get somewhat fired up about the issue, and said, "I get tired of people that are holier than thou because they've been pro-life longer than I have”. His stance has been confusing, saying why he is against abortion fully, he supports the laws that are in place.
Most of the candidates were united in attacking democratic Senator Barack Obama for comments he made about going into Pakistan to pursue Osama Bin Laden. He said if the U.S. had actionable intelligence about high value targets in the mountain on the borders between Afghanistan and Pakistan and the Pakistani government would not act on that, his administration would. The republicans seem to twist around what Obama said and tried to make it seem like he would attack Pakistan.
When asked about their strategy to get the U.S. out of Iraq, once again there was only one republican candidate who voiced a strategy to actually do so, and the was Congressmen Ron Paul. “Just come home. We went in illegally... and we ought to just come home".
