PHOENIX - A key deadline quietly passed overnight, with huge political implications in Arizona and across the country.
Senator John McCain's seat will officially not be up for grabs this November. That deadline passed at midnight and it's important for several reasons, especially for Republicans who are fighting to keep control in the Senate in the upcoming November mid-terms.
Had McCain decided to step aside, it could have created chaos with both Senate seats coming up for election at the same time. Now it's guaranteed Arizona will have at least one Republican senator beyond this fall.
