Republicans are heading into the final weeks of the midterm campaign with the political climate highly in their favor, according to a new Washington Post-ABC News poll. Americans are increasingly frustrated by a lack of economic progress, deeply dissatisfied with the federal government and critical of President Obama's leadership.

For the first time in more than four years, Republicans run about evenly with Democrats on the basic question of which party they trust to handle the nation's biggest problems. Among registered voters, 40 percent say they have more confidence in Democrats and 38 percent say they have more trust in Republicans. Three months ago, Democrats had a 12-point advantage.
