Those who thought 30 percent approval was probably as low as President Bush could go need to think again. According to a just published Newsweek poll, Bush's job approval rating has tumbled to 26 percent, which, as Kos's McJoan points out, approaches Nixonian levels of public support.

She also cites a new ARG poll, which indicates that 45 percent of adults want the House of Reps to begin impeachment proceedings against President Bush (46 percent opposed). And things could get gnarly sooner for the puppetmaster. According to the ARG poll, 54 percent want the House to begin impeachment proceedings against Vice President Cheney. There is already a fair amount of heated discussion in the blogs about the wisdom of impeachment in the context of Democratic '08 strategy, and If this trend persists or grows, it will get even hotter.

How much of the Bush/Cheney free fall can be attributed to rising gas prices? A good question, and Professor Pollkatz's Pool of Polls has a graphic that indicates a pretty clear relationship over time.
