And why do they oppose any efforts to prevent vote fraud?
Because Democrats aren't really democrats?
Because they are the only side that cheats.
Unless you mean the Republican side is the only side who cheats, you're lying. Because the bald fact is that if Republicans didn't cheat and surpress the Democratic vote by any means possible, they would never win an election. And its working.
In the past 3 elections, Democratic Senatorial candidates have received 45 million MORE votes than Republican candidates, and yet Republicans have controlled the Senate throughout. Ballots in poor and minority neighbourhoods are several times more likely to be rejected for the most bullshit of reasons, than in Republican districts. Hours in polling places in poor neighbourhoods are restricted so that if someone cannot take time off work to vote for fear of being fired, they'll chose being employed. In Canada, employers are required by law to give you up to three hours off to vote. Not so in America.
In Georgia, if the state employee scrutinizing your ballot decided your signature didn't sufficiently match your voter registration application, your ballot got tossed. Amazingly, this occurred three times as often if your address was located in a poor or minority neighbourghood.
The Courts have decreed that voter ID requirements, polling place hours and locations were specifically targeted to limit the ability of the working poor and minority voters from voting.
This is how Republicans are maintaining power, despite having much lower membership than the Democrats, and substantially fewer voters. In the House, seats are so gerrymandered that Democrats now have to win 57% of the vote to hold the House. Not 51%, 57%.
And now this minority party has gerrymandered the Supreme Court, despite the majority of Americans opposing the partisanship of the Court.
