US Senate -- approval of incumbents, where available.
Approval polls only.
Gray -- no incumbent at risk.
White -- retiring incumbent or (should it happen) an incumbent defeated in a primary, with "D" or "R" for the party in question.
Yellow -- incumbent under indictment or with a terminal diagnosis short of the completion of his term, with "D" or "R" for the party in question.
Light green -- Republican incumbent apparently running for re-election, no polls.
Light orange -- Democratic incumbent apparently running for re-election, no polls.
Blue -- Republican running for re-election with current polls available.
Red -- Republican running for re-election with current polls available.
Tan -- incumbent Senator credibly running for another office. Approval and party (D, R) shown
Intensity percentage shows the first digit of the approval of the incumbent Senator --
"2" for approval between 20% and 30%, "3" for approval between 30% and 39%... "7" for approval between 70% and 79%.
Numbers are recent approval ratings for incumbent Senators if their approvals are below 55%. I'm not showing any number for any incumbent whose approval is 55% or higher because even this early that looks very safe.
An asterisk (*) is for an appointed incumbent (there are none now) because appointed pols have never shown their electability.
Approval only (although I might accept A/B/C/D/F) -- not favorability. I do not use any Excellent-Good-Fair-Poor ratings because "fair" is ambiguous. A fair performance by a 7-year-old violinist might impress you. A 'fair' performance by an adult violinist indicates something for which you would not want to buy a ticket.
NO PARTISAN POLLS.

... Senator Rand Paul is no longer running for the Presidency.
The greatest evil is not now done in those sordid "dens of crime" (or) even in concentration camps and labour camps. In those we see its final result. But it is conceived and ordered... in clean, carpeted, warmed and well-lighted offices, by (those) who do not need to raise their voices. Hence, naturally enough, my symbol for Hell is something like the bureaucracy of a police state or the office of a thoroughly nasty business concern."
