This is not a republican. And republicans had presidents before this one. But they did nothing.
President Johnson's March 15, 1965 Voting Rights Speech to Congress
Ha ha ha,
Democrats had majority control of congress at the time, not only that Republicans voted yes at a much higher rate than the Democrats for the Civil Rights act.
The Daily Signal
Excerpt:
The House passed the bill after 70 days of public hearings and testimony in a 290-130
vote. The bill received 152 “yea” votes from Democrats, or 60 percent of their party, and 138 votes from Republicans, or 78 percent of their party.
These percentages include four vote categories—“yea,” “nay,” “present,” and “not voting.”
In the Senate, the bill faced strong and organized opposition from Southern Democrats. Influential
senators like Richard Russell, Strom Thurmond (who would
soon switch to the Republican Party), Robert Byrd, William Fulbright, and Sam Ervin joined together to launch a
filibuster that
lasted for 57 days.
Russell, a Democrat from Georgia, at one point
argued that the bill would lead to the destruction of the South’s “two different social orders” and result in the “amalgamation and mongrelization of our people.”
After some changes were made to the bill and the filibuster ended, it passed the
Senate with a 73-27 vote. About 82 percent of Republicans in the Senate voted for the bill, as did 69 percent of Democrats. The
amended Senate bill was then sent back to the House where it passed with 76 percent support from Republicans and 60 percent support from Democrats.
