Yup. When Newt gained ground Santorum, Paul and Santorum attacked him endlessly. Remember how Santorum avoided attacking Romney until Newt was all but out of the race? Ron Paul spent millions with his Anti-Newt video online.
Yeah they all were like that except Perry. Perry was attacking Romney but he faltered away. Newt then took over. If Bachmann had gone aggressively against Romney maybe she might have done better. But there was a rooting section against her from the start.
