A catastrophic outcome for the Dems is catastrophic for all of us. We all live in this house that will burn to the ground under the GQP. We cannot say the Dems have not been working very hard to get Manchin and Sinema to vote with them. Manchin is likely compromised by Trump (see the Medium article I posted, at bottom, for link to video footage about this).
FYI: part of the Russian campaign in 2016 was to depress the Black vote. This is for real and included in the Mueller Report.
