A new GOP internal poll in Kansas finds Barbara Bollier (D) leading Roger Marshall (R) in the U.S. Senate race, 45% to 42%, the Sunflower State Journal reports.

The Kansas City Star reports on two internal polls showing the U.S. Senate race between Roger Marshall (R) and Barbara Bollier (D) is very close.

A poll done for Bollier gives her a 45% to 43% lead, while a poll done for Marshall has him ahead 43% to 39%.

Former Sen. Nancy Kassebaum (R-KS) endorsed Barbara Bollier (D) for the Senate seat that she held for 18 years, the Kansas City Star reports.

This is the second time in two election cycles that Kassebaum has endorsed a Democrat in a statewide race, announcing her support for Laura Kelly (D) in the 2018 race for governor.

A new Public Policy Polling survey in Kansas finds Roger Marshall (R) leading Barbara Bollier (D) by just one point in the U.S. Senate race, 44% to 43%.

In the presidential race, Donald Trump leads Joe Biden, 50% to 43%.

Roger Marshall (R) has won the Kansas Senate Republican primary by defeating Kris Kobach (R), according to Decision Desk.

Marshall will face Barbara Bollier (D) in the general election.

Politico: “Republicans are about to learn if they have a serious problem in Kansas — and another major threat to their teetering Senate majority.”

“In Tuesday’s primary, GOP voters will decide between hard-line conservative Kris Kobach and Rep. Roger Marshall as their nominee for an open Senate seat. Democrats haven’t won a Senate race in Kansas in nearly a century. But both parties think Kobach as the nominee would put the race squarely on the map, stretching Republican resources thinner as they’re already spending to protect a half-dozen vulnerable incumbents.”

New York Times: “Mr. McConnell and other Senate Republican leaders have made urgent pleas to the president to block Mr. Kobach by endorsing one of his opponents, Representative Roger Marshall. But Mr. Trump has so far declined to do so, and his aides said they had no plans to change course. Compounding the frustration of Capitol Hill Republicans, White House aides have refused to tell Mr. Kobach, a longtime booster of Mr. Trump, to stop using the president’s imagery in his campaign materials.”

“With a number of incumbent Senate Republicans trailing in polls, and being out-raised by their Democratic rivals, they have little margin for error as they seek to protect their 53-47 majority. And because of Mr. Trump’s broad unpopularity, and a health crisis that has devastated the economy, even a deeply conservative state like Kansas, which has not sent a Democrat to the Senate since the 1930s, is no sure thing for Senate Republicans this year.”

“President Trump indicated to associates during a flight on Air Force One on Wednesday that he would not intervene in the US Senate Republican primary in Kansas despite the fears among top Republicans that the state could elect a nominee who will lose the seat and thus the Senate,” CNN reports.

“While the GOP establishment has long been alarmed by the prospect that conservative firebrand Kris Kobach could win the primary on Tuesday only to lose the general election in November, Trump has so far not endorsed its favored candidate, Republican Rep. Roger Marshall.”

Sen. Pat Roberts (R-KS), who is retiring, officially endorsed Rep. Roger Marshall (R) in next month’s Kansas primary, the Kansas City Star reports.

His support comes as Marshall is locked in bitter race with rivals Kris Kobach (R) and Bob Hamilton (R).

“A mysterious new super PAC with links to Democrats released a TV ad on Wednesday meddling in next month’s Kansas Republican Senate primary,” Politico reports.

“The ad is engineered to drive conservative voters toward Kobach. A narrator in the ad calls Kobach ‘too conservative’ because he ‘won’t compromise’ on building President Trump’s border wall or on taking a harsher stance on relations with China. By contrast, the ad labels Marshall as a ‘phony politician’ who is ‘soft on Trump.'”

“Kansas Democrat Barbara Bollier raised more in a three-month period than any candidate in Kansas history for federal, state or local office,” the Kansas City Star reports.

“Bollier’s U.S. Senate campaign took $3.7 million in contributions from April through June, a quarterly record in the state.”

“An anonymous group with ties to Republicans has just emerged with the apparent aim of targeting Senate candidate Kris Kobach of Kansas,” CNN reports.

“Kobach is an anti-immigration firebrand and voter-fraud crusader whose primary campaign has sparked fears among GOP leaders that he could jeopardize a seat crucial to keeping control of the chamber.”

A new Civiqs poll in Kansas finds Barbara Bollier (D) in a dead heat in the U.S. Senate race against any Republican nominee.

Bollier leads Kris Kobach (R), 42% to 41%, trails Roger Marshall, 41% to 42%, and leads Bob Hamilton, 41% to 40%.

“It has been 88 years since Kansas last sent a Democrat to the United States Senate — one of only three Democrats ever to represent the state in the upper chamber. But this year, in a challenging and unstable political environment for Republicans, party leaders are growing fearful that this reliably Republican stronghold will instead become an expensive, high-stakes battleground that could determine the balance of power in Washington,” the New York Times reports.

“Ahead of the August primary, Democrats have largely rallied around Barbara Bollier, a retired anesthesiologist who was until recently a Republican. Republicans, meanwhile, are locked in an intraparty competition that has all of the trappings of a full-out brawl: attack ads, bitter recriminations between the candidates and a party chair who tried to intervene and sparked backlash. At the center of the fireworks is Kris W. Kobach, a hard-line Trump supporter who has been an incendiary presence in Kansas politics for years.”

A new National Republican Senatorial Committee poll in Kansas finds Roger Marshall (R) leading Barbara Bolier (D) in the U.S. Senate race, 46% to 35% with 18% undecided.

However, the race is effectively tied with Kris Kobach (R) as the GOP nominee: Kobach barely edges Bolier, 44% to 43% with 12% undecided.

“President Trump recently encouraged Secretary of State Mike Pompeo to reconsider running for the U.S. Senate in Kansas but Pompeo rebuffed the request,” the Washington Post reports.

“Trump spoke to Pompeo about making a bid for the seat during a one-on-one meeting at the White House about two weeks ago, both people said, suggesting that Pompeo could definitely keep the seat for Republicans if he ran.”

“Trump’s request underscores the growing nervousness among Republicans that they could lose control of the Senate in this fall’s election and that a once safe Kansas seat could now be in play.”
