Fox did not stick a knife in his back. Those shows grab the headlines and talk about them. The headline was about New Hampshire polls. So maybe they could have expanded their conversation beyond that headline. But that was the headline. I remember seeing it posted here on FR.
Wallace puts up the quotes from Barnes and Krauthammer as the concervative attitude towards Thompson (which he normally would never do about ‘Fair and Balanced’ FOX). As Fred pointed out that these two gentlemen were not the Alpha and the Omega of the conservative movement, Wallace did his best to shout him down. That was the ‘sticking in the knife’. They clearly are believers in the ‘Golden Rule’. He who has the gold (Murdock) makes the rules.
