"Jim Crow" was a (fictional) meek, subservient black man in a minstrel show dating back to the 1830's, a show popular for a little while in the south. The name eventually transcended the show and came to be used as a demeaning nickname for black men.
The laws known as Jim Crow Laws were a series of state laws passed by southern state legislatures which established segregation in society. The last of them were still in effect in the 1960s, and had lately been called "separate but equal" laws to continue to justify them... and of course, there was separation but little or no equality.
The Civil Rights Act dealt with the last of those laws, superceding them with federal law, which made that kind of state law illegal.
Democrats passed Jim Crow laws, of course, as they were politically in charge throughout the south from about 1896 all the way up through the early 1960's. And while the (majority) Democrat party in congress voted about 40% AGAINST the Civil Rights act in the House and Senate -- and Senator Robert Byrd FILIBUSTERED it for many hours, actually the longest filibuster on record in the Senate -- the minority Republican party voted about 85% FOR it.
In fact, if Republicans had voted against it, they would have added their votes to the 40% of Democrat opposition and been a MAJORITY -- and the CRA simply would not have passed.
And Jim Crow laws, the southern Democrat invention, would have remained in effect.
Democrats passed Jim Crow laws. Republicans were the key to the CRA's passage, which ended them. A Republican, Senator Everett Dirksen of Illinois, WROTE the Civil Rights Act, at the request of JFK.
Joe Biden laments "Jim Crow 2.0". The election laws he is trying to slander have nothing to do with segregation, not even with any unfairness.
If you stipulate the left's absurd claims about election laws making it harder for black people to vote, you have to note that Delaware's EXISTING election laws are harder on black people than any of the proposed NEW election laws in any state.
But of course, these new state laws are NOT hard on black voters... unless you propose that they're too stupid to get ID, too stupid to use a photocopier, etc.
In other words, unless you’re Biden or Harris.
