On Wednesday, long-simmering tensions between West and the party’s vice chair, Cat Parks, boiled over as he called her a “cancer” and “delusional and apparently deranged” amid a dispute over a party committee project. Parks is a cancer survivor. A day earlier, a group of county party chairs called for West’s immediate removal as state party leader, alleging an “outrageous conflict of interest” given that he is now running for governor. West announced last month that he was stepping down as Texas GOP chair, but it is not effective until Sunday, when the State Republican Executive Committee is set to elect his successor. The closing episodes of his chairmanship reflect the sharp-elbowed style West has used in leading the Republican Party in the country’s biggest red state — and how it is likely to follow him as he embarks on his campaign for the Governor’s Mansion.
