It never fails. When the regime of center-right political leader with executive authority begins to implode, the focus is on how and why that person is failing — as it should be. When it becomes clear that a leftist mayor, governor, or president is entering the failure zone, it's because the job is impossible, or the city, state, or nation has become "ungovernable."

We're entering the excuses phase with President Obama (with an important qualifier to be explained later). At the Washington Post's "The Fix" blog yesterday, Chris Cillizza, in a post titled "It’s virtually impossible to be a successful modern president," had a trio of cop-outs at the ready:

Mika Brzezinski: back on the crime beat with another loopy liberal take on reality . . .

Yesterday, the resident lefty on the Morning Joe panel -- defying the facts of the volunteer guard who stopped the Colorado church shooter -- labeled as "the most inane thing" she'd ever heard the notion that one armed citizen could make a difference.

Today, in a breathtaking bit of revisionist history, Brzezinski tried to credit notoriously lax former Mayor David Dinkins rather than Rudy Giuliani for making NYC safe.
