According to Gallup,
Congress's approval rating went up 12 points last month and another 8 points this month. At this rate, they might even hit 50% sometime this spring! Apparently the American public likes the idea of better healthcare for kids, fighting discrimination against women, and stimulus spending to slow the course of the financial meltdown.
It's also worth noting that although most of the increase is due to Democrats being happier with Congress than in the past (no surprise), approval among independents has doubled. Republicans are still unhappy, of course, but no more so than in the past. Apparently all that talk radio bloviating about incipient socialism hasn't had much effect even on conservatives.
