In an ongoing battle between Republican front-runner and the Republican Party establishment, Donald Trump penned a scathing opinion piece, writing that a "planned vote" in Colorado had been "cancelled," causing Republican voters to be "sidelined."
The piece, published in the Wall Street Journal, is the latest move by Trump, who won zero delegates in Colorado after a series of local party conventions, to paint the process as tainted.
