the Left
I'm not criticizing the left, look at the specific things I've criticized and who implements them. Liberals are not the left.
All we ask is to help us win this election
The dems would rather lose than do what their electorate demands, hence the year long genocide they're supporting.
First two years of Obama's first term the dems had 60 in the senate and a majority in the house. Instead of removing the filibuster and doing what people voted for them to do, the dems threw up their hands and said "Joe Lieberman won't let us give you free healthcare" and instead we got Obamacare. They then proceeded to lose the house and senate because that's what happens when you betray your base.
Then in 2020, the same thing played out, instead of whipping the vote and taking Sinema off committee assignments and/or prosecuting Manchin's family for corruption unless they played ball, the dems chose to throw their hands up and said "we're powerless!"
When they couldn't use that excuse due to must-pass bills like budget reconciliation, they blamed the Senate Parliamentarian. Who they appointed. When the Senate Parliamentarian wouldn't do what Bush wanted, they replaced them with someone who would.
The dems aren't powerless, but there's a conflict between the people who vote dem and the corporations who fund them so pretending they are allows them to have their cake and eat it too.
