SEN. Grace Poe will not be anybody’s running mate in 2016 because for her, it’s the presidency or nothing, a source said on Saturday.

The source who asked not to be identified for lack of authority to speak on the matter said Poe is not considering running for vice president. He said the senator believes that running second fiddle to any presidential candidate would not bode well for her political career since she could just be used as a tool to boost somebody’s chances.
