Kyle is retiring here in AZ and Jeff Flake is the likely replacement, which would be a wash, more or less. Indiana has a chance to move right, with Lugar out. Utah will likely return Orin Hatch.
My worry is we return too many establishment R's....we need to shake it up to be sure the T-P House initiatives aren't slowed in the Senate.
My best estimates:
AZ = Flake (RINO-Borders Squish)
CT = McMahon or Shays (RINO/Ultra-RINO)
FL = Mack (RINO-Called AZ Immigration Law like Nazi Germany)
HI = Lingle (Ultra-RINO)
IN = Mourdock (Tea Party)
ME = Likely loss from RINO to Independent (Liberal Dem)
MI = Hoekstra (lean Conservative)
MO = Steelman/Akin (Conservative)
NE = Fischer (Tea Party)
NJ = Kyrillos (RINO)
NM = Wilson (RINO)
ND = Berg (Conservative)
OH = Mandel (Tea Party)
PA = Smith (Conservative?)
TX = Cruz (Tea Party) (if Dewhurst, RINO)
VA = Allen (Conservative)
WV = Raese (Conservative?)
WI = Thompson (RINO)
If we get most of these, at best perhaps 5 or 6 would be a decided improvement, the rest would a slight to negligible improvement.
