Republicans are leading all statewide races by double-digit margins, according to a SurveyUSA poll.
The poll was conducted from Aug. 12 through Sunday for KWCH-TV.
It showed GOP gubernatorial candidate Sam Brownback with 67 percent and Democrat Tom Holland with 25 percent. In the U.S. Senate race, Republican Jerry Moran had 69 percent to Democrat Lisa Johnston's 23 percent.
Republican Kris Kobach had 62 percent to Democratic Secretary of State Chris Biggs' 30 percent. Republican Derek Schmidt had 54 percent to Democratic Attorney General Steve Six's 24 percent.
Republican Ron Estes had 61 percent to State Treasurer Dennis McKinney's 32 percent.
Of those interviewed for the poll, 882 were registered to vote and 588 of those were determined by SurveyUSA to be likely to vote in the Nov. 2 general election.
The margin of error was plus or minus 3.9 percent in the governor's race, 3.8 percent in the senate race, 4 percent in the secretary of state's race, 4.1 percent in the attorney general's race and 4 percent in the treasurer's race.
Roberts to endorse Moran for U.S. Senate
As expected, U.S. Sen. Pat Roberts has endorsed fellow Kansas Republican Jerry Moran for the state's senate seat. Roberts' office announced the endorsement today, but a formal announcement will be made at 1:30 p.m. Monday in Topeka when the two men will hold a joint news conference at the capitol building.
When Roberts became a senator in 1997, Moran succeeded him as the representative for Kansas' 1st Congressional District.
Moran is running against Democrat Lisa Johnston in the Nov. 2 general election.
