Thanks for that detailed explanation, and with the 3 not bound by the primary. And excuse my ignorance - so the “at-large” can be from any district then?
“And excuse my ignorance - so the “at-large” can be from any district then?”
Yes, the Delegate-At Large and Alternate Delegate-At Large may come from any Congressional District. They are typically recruited from the ranks of the Republican Party officials and election volunteers who are deemed to be deserving of meritorious recognition for their work and/or financial contributions to the Republican Party and/or candidates favored by the members of the various Republican local, state, and national committees. In this election cycle many of the Delegates-At Large were handpicked for election at the county conventions and legislative district conventions by the Republican chairmen, committee members, and Precinct Committee Officers (PCO) for their past meritorious service and support of the GOPe candidates, John McCain and Mitt Romney, and for their present support of Ted Cruz.
These party officials have almost entirely filtered out the delegates who supported Trump, Bush, Rubio, Carson, and other candidates at the precinct caucuses, county conventions, and legislative district conventions. Consequently, Ted Cruz is just about the only candidate who has any delegates who are being allowed to go onwards to the Washington State Republican Party Convention despite the popularity of Donald Trump among the Republican voters. Voters are showing up at the local Republican Party headquarters asking for Trump yard signs and bumper stickers, but the Trump campaign has not yet supplied any to the Republican Party headquarters. Instead, the Ted Cruz yard signs and bumper stickers are available at the Republican Party headquarters, but the demand is so small most of the Ted Cruz material is still sitting there unwanted.
