There’s an unintended procedural flaw that could allow some Kansans to vote in both caucuses this week.

Unlike the Democratic caucus Tuesday where participants could register or change their party affiliation at the door, GOP leaders have said anyone who wants to caucus had to be a registered Republican by Jan. 25. The party purchased a list of voters from the Kansas Secretary of State.

However, Christian Morgan, Kansas Republican Party executive director, said that based on the voter records that caucus leaders have dated Jan. 28, they would not be able to tell whether a GOP voter changed his or her registration Tuesday night to Democrat to participate in their caucuses. Those changes probably won’t become official immediately because county clerks have to receive the forms to verify the changes.

Morgan said he expected only a handful of voters to try that strategy.

“If people wanted to switch their voter registration to Democrat to interfere in their caucus, more power to them,” Morgan said. “We know they’re Republicans interested in electing Republicans, and they’re definitely welcome at our caucus.”

Jenny Davidson, spokeswoman for the Kansas Democratic Party, said party leaders hoped anyone who changed affiliation continues to be a Democrat.

“If someone votes in both caucuses, that’s their prerogative,” she said.

At one Lawrence Democratic caucus site, the Douglas County 4-H Fairgrounds, organizers said about 1,250 people filled out a new registration form, but they estimated about 75 percent were Kansas University students who changed their place of voter registration to Douglas County.
