Sen. Ted Cruz (R-Tex.) never seemed to understand this. A CNN poll shows 57 percent oppose Obamacare and 68 percent oppose a government shutdown. For a smart guy, he missed a very basic point.

For those who did not fully comprehend: The president misled us. “Nothing in the health care law guarantees that people can keep the health insurance they already have. Costs can rise, benefits can change and employers can drop coverage.”

It may be hard for non-lawyers to grasp, but this case is extremely difficult to prove, although you’d never guess from reading the report. “The Justice Department filed a lawsuit on Monday in federal court in North Carolina, arguing that several changes to North Carolina’s election law illegally make it harder for black residents in the state to vote.” You have to prove intentional discrimination.

You have to believe the president’s phone call with Hassan Rouhani worried the prime minister. “Israeli Prime Minister Benjamin Netanyahu on Monday warned President Obama not to be fooled by overtures from Iran that have led the administration to pursue talks aimed at halting Iran’s nuclear weapons ambitions. Speaking to reporters in the Oval Office after a meeting with Obama, which lasted more than an hour, Netanyahu said Iran’s ‘conciliatory words must be met with real actions.'”

You figure that Organizing for America is putting the Democratic National Committee out of business. “It is a highly unusual state of affairs for a national party — especially one that can deploy the president as its fundraiser-in-chief — and it speaks to the quiet but serious organizational problems the party has yet to address since the last election, obscured in part by the much messier spectacle of GOP infighting. The Democrats’ numbers speak for themselves: Through August, 10 months after helping President Obama secure a second term, the DNC owed its various creditors a total of $18.1 million, compared to the $12.5 million cash cushion the Republican National Committee is holding.”

Like ordinary Americans, the markets assess just how dysfunctional the federal government is and act accordingly. “U.S. stocks dropped on Monday, taking a little shine off the third straight quarter of gains, as investors worried about a standoff on Capitol Hill and the likely duration of a possible government shutdown.” Wait until the debt-ceiling fight.

Too many conservatives refuse to accept this. “[Sens. Ted] Cruz and [Mike]Lee painted differences in tactics as a lack of principle — or a sign of secret liberalism.This burns bridges. Conservative Republicans get tired of being told they are sellouts because they take a different tactical approach. Which gets us where we are today: Most Republican senators got tired of Ted Cruz and voted for cloture on the continuing resolution. The current form of the Tea Party Whip Operation, it turns out, is an unsustainable way to lead.”
