Trouble is, they want to sue Obama over something that I (and many others) approve of, namely delaying the evil day of employer mandates. Far as I am concerned, we ought to scrap employer mandates entirely. Delaying them for a year or two isn't as good, but it isn't a bad thing.
Obama's methods, pure executive orders, are not kosher, no doubt about it. But, do we really want to bet the government on a matter of process? What he did has broad support. How he did it has broad disapproval. But do we want to make a last ditch stand over methods (how he did it) rather than substance (what he did)?
Most of the unkosher things he has done amount to easing a little of the pain of Obamacare, implementing the Dream Act by executive order after Congress voted it down, sicking the IRS on the Tea Party, Fast & Furious, and Solyndra. The first two have a lot of support. The last three, not so much.
Thomas Sowell, writing in the Union Leader editorial page today, suggests that suing Obama (or impeaching him) will merely distract the easily distracted newsies from covering the Obama administration's real problems (Iraq, Israel, the economy, the deficit, unemployment, Ukraine, China, etc, etc).
