Take a look at the latest polls from the home states of the five remaining candidates for the GOP nomination.

Ted Cruz’s Texas (March 1) – average of 4 polls covering February 19-23: Cruz leads Trump by 5%.

  • Cruz: 33%
  • Trump: 28%
  • Rubio: 17%
  • Kasich: 8%
  • Carson: 5%

John Kasich’s Ohio (March 15) – single poll covering February 16-20: Trump leads Kasich by 5%.

  • Trump: 31%
  • Kasich: 26%
  • Cruz: 21%
  • Rubio: 13%
  • Carson: 5%

Ben Carson’s Maryland (April 26) – single outdated poll covering January 11-16: Trump leads Cruz by 17%.

  • Trump: 32%
  • Cruz: 15%
  • Rubio: 14%
  • Carson: 9%
  • Christie (no longer running): 8%
  • Bush (no longer running): 4%

Donald Trump’s New York (April 19) – single, outdated poll covering January 31-February 3: Trump leads Cruz and Rubio by 18%.

  • Trump: 34%
  • Cruz: 16%
  • Rubio: 16%
  • Christie (no longer running): 11%
  • Bush (no longer running): 7%
  • Kasich: 4%

Marco Rubio’s Florida (March 15) – single poll covering February 21-24: Trump leads Rubio by 16%.

  • Trump: 44%
  • Rubio: 28%
  • Cruz: 12%
  • Kasich: 7%
  • Carson: 4%

Trump is beating Rubio in Rubio’s home state by nearly as much as he’s beating Rubio in Trump‘s home state – whereas Cruz is winning his home state and Kasich is only a few points behind in his. If Rubio dropped out, and half his voters went to Kasich, Kasich would win Ohio. If Kasich dropped out, and all of his voters went to Rubio, that wouldn’t be enough for Rubio to win Florida.

So, of course, Kasich should drop out and endorse Rubio.

Makes sense.
