Someone Explain This 'Shutdown' to Me?

[Rev. Rye]

Could happen, but who is going to run again either Trump or Pence?  Seems like in the past couple weeks they're announcing a new one every day or two.  It will be interesting to see once the primaries start.

It isn't stamped in stone that Trump will be the Republican nominee.  Likely, but his support among mainstream Republicans has been eroding, and it's entirely possible that he could be challenged for and lose the nomination.

I would like to point out that the last time a primary challenge has succeeded was in 1884, and that mostly ended up working because Chester A. Arthur A) was growing ill with nephritis and was keenly aware that he wouldn't have survived a second term, and B) alienated his supporters by reforming the Spoils System.

I'm really not seeing the sort of alienating the base that forced the Republicans to go with James G. Blaine in 1884.
