I wouldn't count on the GOP remaining weak and undisciplined. In the minority, they've demonstrated more discipline than Dems.

Take a look at McClatchy's piece -

'Who's in charge' question looms over Clinton hearing

..[.] If Obama, Clinton and their teams see eye to eye, they could aggressively remake U.S. relations: repairing frayed ties with European allies, channeling tensions that have built up with Russia, and opening a more cordial relationship with the Islamic world.

But if the lines of authority are not clear, the result could be internecine conflict between the White House and the State Department of the sort that plagued both Democratic and Republican administrations of the past, according to current and former U.S. officials.

The question, "who's in charge," will be in the background when the former New York senator appears Tuesday for what's expected to be a friendly reception from her colleagues and a rapid confirmation in the new post. But it will be central to her success or failure as secretary of state.

"This is a really formidable team," said David Rothkopf, a senior Commerce Department official under President Bill Clinton and author of a history of the National Security Council, speaking of Obama's overall appointments.

"The challenge is providing strong leadership for a strong team," Rothkopf said. On the other hand, he added, "What do you want -- a weak team . . . so there are no rivalries?"

Rothkopf said the key will be for Obama, who takes office saddled with an array of urgent foreign policy challenges, to exert strong control over foreign policy, and over his team.

If he does that, "then all these appointments look good," he said. If not, "it could . . . create ego gridlock in the highest reaches of the U.S. policy apparatus."

we'll see how long Clinton will parrot Obama's speaking style and vocabulary .."this defining moment in history"

Ego gridlock ahead.

Well, "You can't vote for war and disown the results"

Agreed.

For the foreseeable future they will be weak and ineffective.

Disagree.  They will figure out pretty quickly that bullying, whining, and strict party unity aren't going to work in the new Congress.  I give them 6 months tops (Senators will probably figure it out faster than Reps because of "institutional memory" and the general structure of the Senate).

At that point the game shifts to maneuvers that will peel off conservative Dems from cloture votes in the Senate in order to embarrass the President or the Congressional leadership (or both, if possible).  The House GOPers will also be trying to peel off conservative Dem votes, but it sheer numbers will make it more of an uphill battle for them and, frankly, Pelosi is better at this sort of rear-guard defense than Reid is.

They'll also be working to find ways to slip poison pills into legislation that they know the Progressive elements of the Democratic Party won't want to vote for.  Again, getting conservative Dems to side with them will be the main tactic for this (and they will probably be able to be more successful in the House at this than with trying to kill legislation outright).

My hope is that the last couple of decades of hyper-partisan Republican action has galvanized enough of the members of the House to make these tactics ineffective, and that sheer numbers in the House will prove to be enough to foil Republicans at this game.  I have no hope for the Senate, except that maybe the Republicans will overstep with their obstruction and manage to lose even more seats in two years.

Over the last few years she has adopted many Republican positions and has reached out to ingratiate herself to the right wing.  Look how she goes out of her way to show how tough she is and how she makes it a point to emphasize the U.S. will still quickly resort to military force (Just today saw Hillary threaten nuclear war against Iran).

Hillary has became a right-winger in many respects.  Or at least she is more friendly with them than she is with the "left wing".  

So of course Republicans are going to be less hostile.  

Republicans have won.  They have moved everyone to the right. Including you.  Including her.
