Please name the 11 seats they gain in the Senate and why for each race. Thank you.
I think someone is just being a good cheerleader. RCP has the Safe seats (and not competing) at 46-37, GOP... to get to 62, the GOP would need a virtual sweep, winning 16 of the 17 "in-play" races... 12 of which are current Dem seats.
17 in play (arranged from best-to-worst polling today for the Dem):
OH: Brown (D)
MI: Stabenow (D)
PA: Casey (D)
MN2: Smith (D)
NJ: Menendez (D)
WI: Baldwin (D)
WV: Manchin (D)
AZ: Open (R)
FL: Nelson (D)
IN: Donnelly (D)
MO: McCaskill (D)
MT: Tester (D)
NV: Heller (R)
ND: Heitkamp (D)
TN: Open (R)
TX: Cruz (R)
MS2: Hyde-Smith (R)
The "Safe" races, none of which flip:
DEMOCRATS (14)- CA: Feinstein (D), CT: Murphy (D), DE: Carper (D), HI: Hirono (D), ME: King (I), MD: Cardin (D), MA: Warren (D), MN1: Klobuchar (D), NY: Gillibrand (D), WA: Cantwell (D), VT: Sanders (I), VA: Kaine (D), NM: Heinrich (D), RI: Whitehouse (D)
REPUBLICANS (4) - MS1: Wicker (R), NE: Fischer (R), UT: Romney (R), WY: Barrasso (R)
35 seats up for a vote in NOV, and it is 26-9, current Dem seats. A tall order for the DNC to play defense.
65 seats are not up for a vote in 2018. Those are 42-23, GOP. The RNC gets to play defense for the next 2 cycles.
