Jim Geraghty of National Review and Greg Corombos of Radio America cautiously welcome polls showing Nevada Sen. Dean Heller winning his race and House Republicans holding a one-point edge in the 66 most competitive districts.  They cringe at allegations the Saudis may have killed journalist Jamal Kashoggi and what it may mean for U.S.-Saudi relations.  And they roll their eyes as Massachusetts Sen. Elizabeth Warren's claims victory in the debate over her heritage because a DNA test showed she was anywhere from 1/64 to 1/1,024 American Indian.
