After a week in which they slept on cots, ordered pizza from a place that could really use a mop and were continually frustrated by Senate Republicans, Senate Democratic leaders previewed a line of attack they are likely to use on the minority party heading into 2008.

"We're all rested and bright-eyed," joked Majority Leader Harry Reid, before launching into an exasperated list of grievences with Senate Minority Leader Mitch McConnell and the GOP.

Aside from being prevented from voting on amendments to the Defense spending bill this week, Reid accused Republicans of delaying votes on the Homeland Security appropriations bill, an education measure on the floor today, and reauthorization of the State Children's Health Insurance Program, a bill the President has promised to veto. The Republicans' "pattern is very clear," Reid said, accusing the GOP of preventing even the ethics and lobbying reform bill to move to a conference committee, a measure Reid said "would change the way Washington does business."

It was the lack of action on the war in Iraq that left the four Democratic leaders -- including Illinois Senator Dick Durbin, New York Senator Charles Schumer and Washington Senator Patty Murray -- most frustrated. Referring to the amendment on which Democrats failed to achieve the 60 votes necessary to move forward, Schumer was adamant. "We are going to bring the Levin-Reed amendment to the floor over and over and over again until we win," he said.

Senate Democrats are next planning to address the war in Iraq when General David Petraeus delivers his update report in September.

Durbin described the situation in the upper chamber as a "breakdown of comity," while Reid blamed Congress' sinking approval ratings on Republicans. Asked whether moderate Democrats and moderate Republicans could get together and move legislation in a bipartisan way, Reid said the Senate GOP doesn't represent mainstream Republican voters. "I believe that there are plenty of moderate Democrats," he said. "The problem is there are no moderate Republicans."

Charges of obstructionism can work in Senate races. Just ask former Senate Democratic Leader Tom Daschle and the man who sits in his seat now, South Dakota Republican John Thune. The netroots are excited by the possibility that some big-name Kentucky Democrat will challenge McConnell in 2008, and if a strong candidate emerges, look for obstructionism to be a central theme. McConnell, along with four other vulnerable senators up in 2008, has already been targeted by the DSCC for standing in the way of Iraq legislation.

However, serving in Kentucky, a state likely to go strongly for the Republican Presidential nominee, may make arguments about McConnell's obstructionism moot. But if the presidential race hinges on Iraq, it could be that, by refusing to let Democrats make decisions about the war, therefore giving them responsibility for its progress, McConnell could be digging his own hole from which he'll have to extricate himself next year.
