"Republicans basically have two choices of how to proceed. Both options have some risk, but one approach almost surely leads to failure.
Draw a line in the sand and pass a strong budget with cuts and meaningful reforms, even if it means the Democrats block the spending bill and cause a shutdown.
Upsides - This approach is more likely to lead to an outcome that reduces the burden of government spending. Moreover, it surely would trigger more activism from libertarians, conservatives, and other supporters of limited government. A victory based on this approach (or even a draw) creates momentum for both the FY2012 budget resolution battle and the debt limit fight.
Downsides - The left, including the establishment press, will portray the GOP negatively. More specifically, they will claim Republicans are "shutting down the government" because of supposedly extraneous issues like abortion (i.e., the funding controversy over Planned Parenthood), the environment (the debate over the "rider" provision to curtail the EPA's power grab), or healthcare (defunding Obamacare).
Do everything possible to avoid a shutdown, even if it means higher spending and no reform.
Upsides - There is no risk of being blamed for a shutdown.
Downsides - This French-army approach basically means that Republicans give up on fiscal policy for the next 21 months. Surrendering to avoid a shutdown means the burden of spending is higher. It means no program reforms or eliminations. Because of this precedent, it is highly unlikely that the GOP could attach meaningful fiscal conditions to the debt limit. Similarly, the loss of momentum would carry over to the budget resolution, undermining chances for fiscal reform in the 2012 fiscal year budget. Last but not least, the "base" would be very disappointed as activists from the Tea Party and elsewhere begin to conclude that fighting against big government is a fool's errand.
Even in the most ideal scenario, using the line-in-the-sand strategy, fiscal conservatives in the House will not get everything they want. The real issue is which side has the upper hand in the negotiations.
The fight-rather-than-surrender approach gives the GOP leverage. They almost surely won't get $61 billion of cuts, but they'll be much closer to that number than with the French-army approach. They won't succeed with all the "riders," but they'll make progress - perhaps temporarily setting aside the Obamacare issue in exchange for clipping the EPA's wings, or gutting Planned Parenthood but letting NPR off the hook."
