POLL SHOWS APPROVAL FOR BUDGET DEAL…. A significant percentage of the national population doesn’t read liberal blogs.

A CNN/Opinion Research Corporation survey released Monday indicates that the budget agreement that prevented a government shutdown is popular, with Americans supporting it by a 58 to 38 percent margin. But there’s a partisan divide, with two-thirds of Democrats and a majority of independent voters backing the deal, and Republicans divided.

If I had to guess, I’d say the deal is popular because (a) it avoided a shutdown, which no one likes; and (b) anytime a bipartisan deal is struck, a lot of folks are inclined to like it, by virtue of the fact that it’s a bipartisan deal.

That said, Democrats also appear to be benefiting more from the agreement. A plurality (48%) of respondents in the CNN give Dems credit for striking the deal, as compared to congressional Republicans (35%), and a majority supports President Obama’s handling of the negotiations, while 44% said the same about the GOP.

The poll also showed strong opposition to the Republican culture-war measures that nearly derailed the deal — a 65% majority supports continued funding for Planned Parenthood, and a 71% majority supports funding the EPA’s enforcement of “regulations on greenhouse gases.”

It’s not as if GOP rhetoric won over much of the American mainstream.

That said, even after all of the Democratic concessions, and the widespread belief on the left that President Obama gave up far too much, the only group of Americans to oppose the budget deal are self-identified Republicans and Tea Party supporters.

These folks really have nothing to complain about — by most measures, they won, and were rewarded with the largest spending-cut package in history — but they’re incredibly hard to please.
