Washington (CNN) - As the House makes its next move in the ongoing fight to end the government shutdown and avoid a default, the House Democratic campaign arm will target Republicans in 60 districts on Wednesday, blaming them for a possible downgrading of the government's rating with a Wall Street bond-firm.
Rating agency Fitch on Tuesday warned of a downgrade of gold-plated U.S. bonds, citing "political brinkmanship" as the reason for the default risk.

Fitch still has the U.S. rated AAA, the highest possible grade, but the country is now on "rating watch negative," meaning that there is increased possibility of a downgrade in the near future.

On the eve of the deadline to raise the debt limit, Congress has yet to reach an agreement.
The Democratic Congressional Campaign Committee will send releases that name 60 Republicans whose "reckless brinkmanship" led to the Fitch warning.
"This is it – today is the last opportunity for Congressman (Name) to end the reckless antics and focus on responsible solutions or else he will have turned America into a deadbeat nation," Emily Bittner of the DCCC says in the release.
It's the latest round of attacks between the two political parties in the Congressional stalemate.
Republican Rep. Steve King of Iowa said Democrats, not Republicans, are the ones at fault for the country teetering on the edge of an important deadline for the economy.
"(House Republicans) put an offer on the table, and then (Senate Majority Leader) Harry Reid rejected it. Then another offer, another offer, another offer. Actually four offers out there before we started in the incremental financing component of this," he said Wednesday on CNN's "Day Day," adding that the President and Senate Democrats have "refused to negotiate in each step of the way."
The Democratic-led Senate refused to take up any measure that tied changes to Obamacare to must-pass spending legislation, a strategy Republicans used to try and chisel away at the president's signature health care law.
