One more state to offer an approval rating for the incumbent Senator up for re-election. Johnny Isaacson is up 38-30 in approval, which indicates that he (1) isn't well known in his own state, and (2) that he isn't trying to get well known and may be relying upon a campaign largely based upon advertising by outside interests (like the Koch syndicate). That's Georgia, a state on the margin of competitiveness.
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 -- Democrat running for re-election with current polls available.
Tan -- incumbent Senator credibly running for another office and not for re-election. Approval and party (D, R) shown With David Vitter retiring after being defeated in a bid for the the Governorship of Louisiana, his seat goes open and no state is shown in this color.
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.

Alabama
Idaho
Iowa
North Dakota
South Carolina
South Dakota
Utah

Kansas
Edge R:
Arizona
Arkansas

Likely D:
Oregon
Washington

*flip (so far all R to D)
New Jersey looks like a fairly sure hold should current, but indicted, Senator Bob Menendez be compelled to resign.
