Or perhaps everybody knows 'command' and 'control' when used for the US senate means '60 seat or higher majority' and I'm just too pig ignorant to know it.
The only pig headed thing is whether you decide to know it now or decide to continue not knowing it.
One thing that may be confusing you is that the misinformation put out by the GOP for the last 11 years has been exploiting this very language to undermine confidence in the Dem party. This is one of their gambits - to say “dems don’t believe this because they didn’t pass this in 2 years - they are not your friends!” When the truth is the Dems could not have passed it because of GOP filibuster.
The misinformation is deliberate and ongoing. The GOP will ALWAYS reference “2 years” to try to lay the story that Dems are not sincere in their beliefs. The Dems, keep bringing in the truth, that they were prevented from passing things. But for many listeners, the misinformation campaign is successful and they think Dems “didn’t have something on the table” because the GOP blocked them from passing it for two years.
It’s a clever strategy, and it works remarkably well. Many Republican and “independant” Americans actually believe that the Dems platform is something different than it is because of how the GOP describes it. It’s deceit, but... here we are.
