According to the final Reuters/C-SPAN/ Zogby poll (David Farrar doesn't rate Zogby, but we do) before the Super Tuesday votes are counted suggests the following:
The final day of polling before Super Tuesday was one of hardening positions in key races across the country, the latest Reuters/C-SPAN/Zogby survey work shows.
Arizona Sen. John McCain continued to dominate among Republicans in the states polled in the surveys, with 50% or more supporting him in New Jersey and New York. Former Massachusetts Gov. Mitt Romney won less than half that in those states.
Romney continued to lead, however, in delegate-rich California, with 40% support in that state, to McCain’s 33%. The Republican race was tighter in Missouri, with McCain ahead with 34% support, former Arkansas Gov. Mike Huckabee in second with 27% and Romney third with 25% support.
On the Democratic side, New York Sen. Hillary Clinton and Illinois Sen. Barack Obama continued to fight neck and neck for their party’s voters and delegates. Obama solidified his lead in California, but Clinton pulled ahead in New Jersey, where the two had been tied in the previous poll.
