Schwarzenegger for Senate?

Politico has an article up with speculation that Arnold Schwarzenegger could run for the US Senate. It's been widely believed that Schwarzenegger was done with politics but he has gotten into a high profile feud with Donald Trump. And he seems to enjoy it. If he wants to continue that, he has no better platform than to run for the Senate. Well, the better platform would be to be in the US Senate. Consider how things have changed in the last eight years.

2010 Democrats: Arnold is an awful evil Republican
2018 Democrats: Anyone who could stick it to Trump is worth a look

2010 Republicans: Arnold is apostate
2018 Republicans: He'd be better than a Democrat. Why not?

I don't think Schwarzenegger could beat Feinstein but he could easily make top two and face off with her in November 2018. If Feinstein were to retire Democrats don't have anyone with a profile like Kamala Harris. Gavin Newsom, John Chiang, and Antonio Villaraigosa could abandon the governor's race but they couldn't transfer their huge war chests. Congressmen like Raul Ruiz or Ami Bera could run but neither has much of a statewide profile. And if Arnold ran as NPP Democrats who won't vote Republican might for him.
