Three “Red” States, those who voted for Donald Trump, have moderate Democratic Senators, who face tough challenges to be reelected.
Those states are Florida and Bill Nelson, Missouri and Claire McCaskill, and North Dakota and Heidi Heitkamp.
Progressives are not necessarily happy with these Senators, as they tend to be far less liberal than most Democrats, but there is no way for the Democrats to succeed and be a majority, if they repudiate those who tend to be more centrist.
So the hope is that Nelson, McCaskill, and Heitkamp can keep their seats, as if they do not, there is no chance of Democrats being a majority in the US Senate, and the potential loss of some of the 49 present Democratic seats would be disheartening.
It is ironic that it seems likely that the Democrats will win Nevada with Jacky Rosen, and Arizona with Kyrsten Sinema, but if they lose any or all three of the presently held Democratic seats, they will end up in negative territory.
Of course, IF the Democrats could produce a “miracle” and win with Beto O’Rourke in Texas over Ted Cruz, and in Tennessee with Phil Bredesen over Congresswoman Marsha Blackburn, along with Nevada and Arizona, the loss of the moderate Democrats would be less significant, as long as at least one of those three seats was retained.
