The GOP has continued its decline since 2004; today just 21% (down from 25% just last month) identify themselves as Republicans, the fewest since September 1983 in ABC/Post polls. Similarly, just 21% say they're confident in the Republicans in Congress "to make the right decisions for the country's future."
