The Republicans in Congress have moved ahead of President Obama in the public's trust to handle the deficit and battled him to parity on the economy. But another issue, Medicare, poses risks for the GOP, and both political parties are losing ground in another sense: A record number of Americans don't trust either of them to cope with the nation's main problems.
The Democrats have bragging rights on the overall measure; Americans pick them over the Republicans to handle the country's main problems by 41 to 32 percent. But 20 percent -- the most in ABC News/Washington Post polls dating back to 1985 -- don't trust either party. Among political independents, rejection of both parties rises to 34 percent.
