Kansas state Sen. Barbara Bollier’s sudden decision this week to switch from the Republican to the Democratic Party may be a one-off.

Or, it could be the beginning of a trend.

In the wake of Bollier’s announcement, Sen. Dinah Sykes, another moderate Republican from Johnson County, is contemplating doing the same thing.

“It has crossed my mind,” Sykes said.

Also considering a switch: Rep. Stephanie Clayton of Overland Park. “I am looking at options,” she said Thursday. Also Thursday, Rep. Joy Koesten, a Leawood Republican, said she was switching. Earlier this year, it was Sen. John Doll of Garden City leaving the GOP to be independent Greg Orman’s running mate.

Other Republicans are also considering their futures.

So is this the beginning of a significant political realignment in the state that could lead to the eventual extinction of moderate Republicans? Or is this a mere blip on Kansas’ always evolving political radar screen?
