Centrist Sen. Blanche Lincoln (Ark.) on Wednesday asked arguably the most contentious question during a discussion between Senate Democrats and President Barack Obama, hitting at conservatives and liberals.

Lincoln, who faces a tough reelection fight, asked Obama to push back against “people at the extremes” of both parties, especially against Democrats “who want extremes.”

She also took a swipe at Obama’s White House, referencing a constituent who “fears that there’s no one in your administration that understands what it means to go to work on Monday and make a payroll on Friday.”

Lincoln faces a steep reelection bid in 2010. She trails the likely Republican nominee, Rep. John Boozman, by 23 points and has only a 27 percent approval rating in a recent poll.

WASHINGTON — The US debt is on track to hit a congressionally proposed debt ceiling of 14.3 trillion dollars by the end of February, the Treasury said Wednesday, a day ahead of a key vote to raise it to that level.

“Based on current projections, Treasury expects to reach the debt ceiling as early as the end of February. However, the government’s cash flows are volatile, making it difficult to forecast a precise date,” the Treasury said in a statement.

The current limit on the public debt of the United States is 12.374 trillion dollars.

The US debt exceeded 12.349 trillion dollars on Monday, according to Treasury data.

Moody’s Investors Service fired off a warning on Wednesday that the triple A sovereign credit rating of the US would come under pressure unless economic growth was more robust than expected or tougher actions were taken to tackle the country’s budget deficit.

In a move that follows intensifying concern among investors over the US deficit, Moody’s said the country faced a trajectory of debt growth that was “clearly continuously upward”.
