Many of the Democratic senators in the red states are either "conservative" Democrats, or among the most popular senators in the country. People Nelson, Byrd, Bayh, or the North Dakota senators would be extremely difficult, if not impossible, to topple.

Your post was accurate, but I do so hope to one day see Byrd topple over in the Senate, live on CSPAN.

While the Democrat Senators from the Blue and purple states may be popular, very few of them are "conservative". Only Nelson from NE and Landrieu from LA could be classified as "moderates" in my viewpoint, the rest vote like liberals. Here is the data:
