Trump has pundits talking about politics as physics.

Yesterday on "This Week with George Stephanopoulos":

GEORGE STEPHANOPOULOS: [Donald Trump is] just about everywhere right now. And it certainly seems to be working so far, leading, you know, the lead, which a lot of people thought would dissipate, solidifying across the summer.

NANCY GIBBS: When you talk about politics like physics, with immutable laws, with him, everything that was supposed to sink him has lifted him instead.

 Yesterday on "Meet the Press":

SUSAN PAGE: I think that we've been wrong from the start about Trump and the nature of his appeal and the ceiling that he's got....

AMY WALTER: ... I think Susan's right, that all of our assumptions have been sort of blown up in our face. But some of this, still, we still have to go back to political physics. There are laws of gravity that still kick in at some point....

CHUCK TODD: Apparently we're Mars, not Earth anymore. The atmosphere is just different.

AMY WALTER: We're just floating--

CHUCK TODD: Gravity is not quite as strong on this planet we're on....

And while we're up there with the planets, Joe Biden is bringing out the astronomy metaphor. This morning at Politico: "Potential Biden run divides Obama orbit."
