More than raising her profile, Clinton is getting her political hardball muscles back into shape by sneaking in a few spring training innings. She hit the surging Sen. Bernie Sanders (I-Vt.) with a line drive straight to his likability, electability and “not-a-team-player” soft spot. Then she worked over the umpires a bit by going after Facebook, its founder and the platform’s predicted influence on the 2020 election.

The intended message seemed to be “I’m tough, I’m proven, I’ve got the massive support to help beat Trump — and I’ve learned from my mistakes.”

If she truly has learned something, then having Clinton entertain the thought of “saving” the Democratic ticket as a vice presidential running mate could be a brilliant political move. Some of her closest allies have been appointed to the committees overseeing rules and party platforms for this summer’s Democratic National Convention.

Biden, still nominally the party’s front-runner, has a list of negative issues to overcome. Clinton could help him erase or mitigate all of them, in one way or another.
