What was the biggest story last week? Readers had a lively debate. Three readers’ answers were particularly cogent.

Jkk1943 argued:

The circuit court decision declaring the individual mandate unconstitutional was the most important event of the day, maybe even the decade. First the appeal court decision ensures that the Supreme Court will take up the case before the election. Second, if the Supremes declare the mandate unconstitutional, it will be a “body blow” to Obama’s reelection campaign because it will “cement” the growing impression of Obama’s incompetence. You can just imagine the GOP talking points : “He spent a whole year passing a law that we opposed, a law that divided the country, a law that took our focus off job creation, a law that was found unconstitutional.” Is this a man the voters should entrust with a second term?

Others thought it was the Standard & Poor’s downgrade. Statistquo wrote:

Obama’s reaction to the S&P downgrade is the most significant event. Other events are part and parcel of the partisan nature of politics in D.C. But the S&P downgrade is a nonpartisan action, which provokes partisan or self-serving responses, like Obama’s and Michele Bachmann’s nonsensical remarks.

Because of the nonpartisan and unprecedented nature of S&P’s decision, ... the presidential candidates, including Obama, will not want to bring the subject of S&P up, . . . [unless] they put their respective spin machines on overdrive. Now that Bachmann has reached the first tier, expect her to be asked why not voting for the debt-ceiling increase, even if ‘cut, cap and balance’ were passed, makes any fiscal or economic sense.

‘Downgrade’ will soon eclipse ‘bailout’ as U.S. politics’ most detestable word.

DavidHolmes1 gave the nod to Matt Miller: “Politically, the most important event may have been Matt Miller’s column . . . savaging the President in VERY blunt terms. If this reflects the feelings of any substantial portions of the president’s base, he’s in deep yogurt.”

All of these observations have great merit. Seeing Bachmann grilled on the Sunday shows on the debt-ceiling vote and Obama’s approval drop to 39 percent in Gallup suggests these and other commenters have things pegged about right.
