How many Senate Republicans are going to rebel against Trump's border emergency?

The cake appears baked on the privileged resolution of disapproval about President Donald Trump's use of a national emergency declaration to secure the money he wants to build a border wall on the southern border.

After the House majority approved the resolution with 245 votes -- including 13 Republicans -- the Senate is now set to vote on it in the coming days. And the question is not if the resolution will pass, but how many Republicans will break from Trump and support it.

"I think there will be 10 Republican 'no' votes. Possibly more," Kentucky Sen. Rand Paul said Monday. "If (you) look at the history of not only our government, but other governments around the world, governments that begin to be run by emergencies, really bad things can happen."

Ten GOP votes for the resolution -- and against Trump's use of national emergency provisions to fund it -- would be a major rebellion against the President, the likes of which we haven't really seen so far in Trump's tenure. (There are four official "yes" votes among Republicans as of Tuesday: Paul, Maine Sen. Susan Collins, Alaska Sen. Lisa Murkowski and North Carolina Sen. Thom Tillis.)

That rebellion is all the more remarkable when you consider that a Senate vote in favor of the disapproval resolution is entirely symbolic. Assuming the measure passes the Senate, it will go to Trump's desk, and he has already made clear many times that he plans to veto it. Once that happens, it will be kicked back to Congress, which would need two-thirds majorities in both chambers to overturn the veto. And the votes for a veto override just aren't there.

If you are a Senate Republican voting for this resolution, then, you know you are doing so without any realistic chance that Trump won't get what he wants anyway. And Trump hasn't exactly been shy about his desire for Senate Republicans to stand strong against the resolution.
