House and Senate Concurrence with Presidents: Eisenhower - Obama
"Vote concurrence is measured by the number of times a majority of members of Congress vote with the president's position on roll call votes. Member concurrence is the percentage of members who agree with the president's position on a roll call vote. Unlike the usual scholarly focus on success or support, the concurrence measures acknowledge that it is impossible to judge who influenced whom." -- Ragsdale, Vital Statistics on the Presidency
