UNDATED -- John McCain and the Republican National Committee have dramatically ramped up their spending in the campaign's final hours. They're now matching Barack Obama ad for ad, if not exceeding him, in key battleground markets in states such as Florida, Ohio, North Carolina, Virginia and Pennsylvania.
After months of planning, the Republican Party has launched the last stage of its vaunted "72-hour program," when volunteers descend on competitive states for the final stretch.
Democrats, meantime, have unleashed their "persuasion army" of backers, people who'll be scouring their own backyards to encourage neighbors to back Obama.
Obama's camp reports that Saturday was it largest volunteer day yet, with more volunteers showing up to work the phones and walk neighborhood precincts than ever before in the campaign. An Obama spokesman says, "Our volunteers are completely engaged."
McCain's crew says its are, too.
