<P> Lobbying support for the Civil Rights Act was coordinated by the Leadership Conference on Civil Rights, a coalition of 70 liberal and labor organizations . The principal lobbyists for the Leadership Conference were civil rights lawyer Joseph L. Rauh Jr. and Clarence Mitchell, Sr. of the NAACP . </P> <P> Johnson, who wanted the bill passed as soon as possible, ensured that the bill would be quickly considered by the Senate . Normally, the bill would have been referred to the Senate Judiciary Committee, chaired by Senator James O. Eastland, Democrat from Mississippi . Given Eastland's firm opposition, it seemed impossible that the bill would reach the Senate floor . Senate Majority Leader Mike Mansfield took a novel approach to prevent the bill from being relegated to Judiciary Committee limbo . Having initially waived a second reading of the bill, which would have led to it being immediately referred to Judiciary, Mansfield gave the bill a second reading on February 26, 1964, and then proposed, in the absence of precedent for instances when a second reading did not immediately follow the first, that the bill bypass the Judiciary Committee and immediately be sent to the Senate floor for debate . </P> <P> When the bill came before the full Senate for debate on March 30, 1964, the "Southern Bloc" of 18 southern Democratic Senators and one Republican Senator led by Richard Russell (D - GA) launched a filibuster to prevent its passage . Said Russell: "We will resist to the bitter end any measure or any movement which would have a tendency to bring about social equality and intermingling and amalgamation of the races in our (Southern) states ." </P> <P> Strong opposition to the bill also came from Senator Strom Thurmond (D - SC): "This so - called Civil Rights Proposals, which the President has sent to Capitol Hill for enactment into law, are unconstitutional, unnecessary, unwise and extend beyond the realm of reason . This is the worst civil - rights package ever presented to the Congress and is reminiscent of the Reconstruction proposals and actions of the radical Republican Congress ." </P>
