Both parties will nominate candidates for the June 25 special election for the 4th District being vacated by Buck. Whoever wins that contest to fill out the remaining months of Buck’s term could have an easier path to winning the election in November to serve a full two-year term representing the 4th District in Congress.

That’s left Boebert in a bit of pickle and with a tough decision to make.

She could resign from her House seat early and seek the GOP nomination in the special election for Buck’s seat, hoping it would better position her for winning the two-year term in November.

The problem with doing that is it would further eat into the House GOP’s narrow majority.

So Boebert can’t run in June 25 special election, without first resigning from her current position in CO-3.
Since she can’t hold two House positions at once.

Questions — can she resign in June, closer to the special election?
As for “candidates” Are both parties nominating ONE candidate, or multiple?
