BELTON, Mo. — Republican John McCain has a $47 million budget for October, but his campaign insists he will have enough to overtake Democrat Barack Obama and his deeper pockets.

A day after Obama announced a record $150 million raised last month, McCain's campaign disclosed yesterday it spent $37 million in September out of the $84.1 million in taxpayer funds it has accepted for the general election. Obama opted out of public financing and can raise and spend unlimited amounts.

McCain campaign manager Rick Davis vowed that the GOP presidential nominee has the resources — combined with aid from the Republican National Committee — to wage an effective ad campaign and get-out-the-vote effort in the states won by President Bush in 2004 and 2000. McCain also plans to compete in Pennsylvania and New Hampshire, both won in 2004 by Democrat John Kerry.

"We've got to win one of the three or four big states in play or a combination of any two of the littler ones," Davis said. Campaign spokesman Tucker Bounds added Virginia, North Carolina and Nevada — where Obama is running aggressively — "will not be taken for granted" by McCain.

The national party raised a record $66 million in September and is on pace for another record-breaking month, said RNC spokesman Alex Conant.

For his part, McCain told a crowd here in this Kansas City suburb that Missouri is a "must win" for him. McCain's travels yesterday took him to two counties won by Bush: Cass, where Belton is located, and St. Charles.

McCain tried to appeal to voters' pocketbook concerns by saying Obama's goal is to redistribute income. In St. Charles, northwest of St. Louis, he said Obama would offer tax credits to people who don't pay taxes, which McCain decried as "just another government giveaway."

Obama spokesman Hari Sevugan said McCain is "flailing" with a new charge every day. Seeking to link McCain to President Bush, Sevugan said the GOP nominee "hasn't found a compelling message to persuade voters that he is offering something other than four more years of the same failed policies."
