A new Mason Dixon poll in Nevada finds either Sue Lowden (R) or Danny Tarkanian (R) would unseat Sen. Harry Reid (D-NV) if the election were held today.
Lowden tops Reid, 49% to 39%, while Tarkanian beats Reid, 48% to 43%.
Though Nevada voters are certain they don't want to re-elect Reid, they're undecided about who should be the Republican nominee. In a GOP primary, Lowden edges Tarkanian, 23% to 21%, with 44% undecided.
