Edwards Forges Ahead

From CBS News' Aaron Lewis:

STORM LAKE, IOWA -- John Edwards continued to push toward caucus day in Storm Lake this morning by again telling caucus-goers that he is the fighter in the Democratic race.

Edwards questioned whether other candidates would, in fact, be able to take on corporate interests.

"If they don't take it personally, if it's academic, if it's intellectual, if it's political, the first time the tough fight comes, they will do the political thing," said Edwards. "You can take that to the bank."

Meanwhile, an Edwards official tells CBS News that the campaign plans a couple of big ad buys in the final hours before the Iowa caucus.

According to the official, Edwards intends to run a full-page ad in tomorrow's Des Moines Register. The campaign has also bought 60 seconds of ad time on all three local network affiliate evening newscasts on BOTH Wednesday and Thursday nights.

Two more notes: Edwards was introduced by Ben "Cooter" Jones of "Dukes of Hazzard" fame. Jones is a former congressman from Georgia and has consistently campaigned on Edwards' behalf in rural areas. Edwards also told the audience that his parents Bobbie and Wallace will join him on the trail tomorrow.
