From The Kansas City Star:

State Sen. Bollier raised $2.35 million during the first three months of 2020 in her quest to become the first Kansas Democrat elected to the U.S. Senate since 1932. The Mission Hills Democrat, who left the Republican party at the end of 2018 because of opposition to President Donald Trump, more than doubled her fundraising in the fourth quarter of 2019, when she collected $1.17 million. It puts her six-month take at roughly $3.5 million. Bollier’s strong showing will likely fuel national Republicans’ anxieties about the race to replace retiring GOP Sen. Pat Roberts.

Republicans are anxious because they have no idea who the Republican candidate will be going into November. Their field is large:

David Lindstrom, former county commissioner of Johnson County, Chiefs football player

Susan Wagle, current Senate President

Kris Kobach, former Secretary of State, last ran for State Governor

Bob Hamilton, self funding millionare owner of a plumbing firm

Roger Marshall, Congressman from Kansas first district

Because of the size of the field, there is a lot of uncertainty as to who will be their candidate, and with the Kansas primary happening in August, there will be less time to quickly unify around a candidate. After Republicans failed to recruit Secretary of State Mike Pompeo to come home and run for US Senate, everything went up in the air.

National Republicans dislike the idea of spending significant resources in a state like Kansas. Too bad.
