Democrats are dwindling in Wyoming. A primary election law further reduces their influence

In Wyoming, the state that has voted for Donald Trump by a wider margin than any other, overwhelming Republican dominance may be even more cemented-in now that the state has passed a law that makes changing party affiliation much more difficult.

Tuesday’s primary will be the first election since the law took effect.

As Wyoming Democrats face difficulty fielding viable candidates at all levels, many Democrats have been switching their registration to vote in more competitive Republican primaries, then changing back for the general election.

Republicans decided they’d had enough. The Wyoming Legislature, where the GOP controls over 90% of the seats, passed legislation last year banning voters from changing their party registration in the three months before the August primary.
