ABC News’ Rick Klein reports: Though much has been made of national Democrats’ money edge over Republicans this year, the race-by-race picture suggests a more complicated story. An official with the National Republican Congressional Committee sends on this report, tallying up the cash-on-hand figures of GOP candidates in House races, as of the beginning of the year. All told, 126 House Republican challengers — that’s those running in open seats or against Democratic incumbents — reported having at least $100,000 in their campaign accounts. Forty-two of those have at least $200,000, and 10 have at least $500,000.UPDATE: After this item posted, several errors in the numbers were corrected. The actually number of House GOP challengers with more than $100,000 in their accounts at the end of the year was 118. There’s some overlap in competitive primaries. But the numbers generally support the view voiced by Republicans that they expect to put between 80 and 90 Democratic-held seats in play. They need to pick up 40 seats this year to take back control of the House. And even candidates generally considered safe — such as Rep. Patrick Kennedy, D-R.I., and Rep. David Wu, D-Ore. — are likely to face well-funded challengers this year. “The playing field continues to expand and Democratic incumbents who were once deemed ‘safe’ will have to fight for their political lives this fall. These numbers are evidence that Republican candidates will have the resources to compete and win in dozens of races,” said Ken Spain, an NRCC spokesman. For their part, officials with the Democratic Congressional Campaign Committee say they’re well-prepared for the challenges. For starters, the DCCC had $16.7 million on hand as of Jan. 1 — compared to the NRCC’s $2.7 million — money national Democrats can use to prop up incumbents who run into trouble. The DCCC’s “Frontline” program to protect endangered incumbents now features 42 members. Almost all have more money than their challengers, and 36 of them have more than $500,000 banked, according to data compiled by the DCCC. Said spokesman Ryan Rudominer: "The DCCC is aggressively raising the resources needed to hold House Republicans accountable for trying to turn back the clock to the failed Bush policies that left us with an economic catastrophe."
