I doubt they care one whit. There are ZERO honorable democrats. Some might flip for expediency, but all of them are swamp creeatures.
The defense is playing to the public, hoping to win at the November ballot box. The impeachment case is just the current "stage" for conducting the polkitical battle. The DEMs chose this battleground.
I did not see Manchin or Jones vote against Dem motions yet. Dem senators voting for acquittal? Believe it when I see it.
