Aug 8 (Reuters) - Republican candidates backed by Donald Trump clung to small leads in closely watched races in Ohio and Kansas on Wednesday, with the narrow margins serving as encouraging signs for Democrats heading into November's elections.
Republicans looked likely to hold onto a U.S. House of Representatives seat in a reliably conservative district in Ohio, where Troy Balderson led Democrat Danny O'Connor by about 1,700 votes in a special election. The final result could be days away as state officials count more than 8,000 provisional and absentee ballots.
In Kansas, staunch Trump ally and conservative firebrand Kris Kobach held a lead of less than 200 votes over current Governor Jeff Colyer, in a primary race that could take days or weeks before a final result is determined.
The narrow margin in Ohio - less than 1 percentage point separates Balderson and O'Connor - is little comfort for Republicans looking ahead to the Nov. 6 vote, as they outspent Democratic groups by more than 4 to 1 to retain a seat they have held for three decades.
"Moving forward, we cannot expect to win tough races when our candidate is being outraised," said Corry Bliss, executive director of the Congressional Leadership Fund, a Republican Super PAC. "Any Republican running for Congress getting vastly outraised by an opponent needs to start raising more money."
Democrats performed dramatically better than expected in the last federal special election before the midterms, when Republicans are defending majorities in both the House and Senate.
"This gives me optimism," Democratic National Committee Chairman Tom Perez told CNN on Wednesday.
Trump took credit for Balderson's lead, writing on Twitter that his fellow Republican's campaign took "a big turn for the better" after he campaigned for him in the district on Saturday.
Other Republicans, including Vice President Mike Pence and Ohio Governor John Kasich, had also rushed to Balderson's aid in a district Kasich once represented.
Tuesday's vote mirrored special elections through 2017 and 2018, with suburban and urban turnout rates that have favored Democrats exceeding turnout in rural areas where Trump has a higher level of support.
"As we've seen all along, Trump's support is rock-solid with a certain percentage of the base. Yet he still appears unable to widen that constituency, either in approval rating or coattails,” said Joe Brettell, a Republican strategist based in Texas.
Trump won the district by 11 percentage points in the White House race in 2016. Republican Pat Tiberi resigned before finishing his term, triggering the special election.
"Complacency is the thing we're most concerned about as a party. ... We have to wake up our voters and let them know you've got to fight for this comeback," Republican National Committee Chairwoman Ronna McDaniel said in a Fox News interview.
The Ohio secretary of state's office said it could not yet declare a winner. Absentee and provisional ballots cannot be counted for 11 days; an automatic recount occurs if the margin is within 0.5 percent of votes cast.
On Wednesday, O'Connor declined to say whether he would seek a recount if one was not automatically triggered. No matter the outcome, he and Balderson will face off again in November to serve a full two-year term.
Democrats need to win 23 more seats in the House and two in the Senate to control Congress and put the brakes on Trump's agenda. All 435 House seats, 35 of 100 Senate seats and 36 of 50 governors' offices are up for grabs in November.
KANSAS RACE NEARLY DEADLOCKED
Kobach, Kansas' secretary of state who was endorsed by Trump in the waning days of the primary race, and Colyer each had about 41 percent of the vote on Wednesday.
Kansas state law allows for a recount if the vote margin is within half a percentage point, but the candidate has to request the recount. Absentee ballots must be postmarked by Tuesday and received by Friday; it is unknown how many ballots may be outstanding.
The recount process could take weeks, and could be complicated as different counties in Kansas use different voting systems, said Patrick Miller, a political science professor at the University of Kansas.
“There is the potential out there for a recount to shift a number of voters given the margins,” Miller said.
Democrats are hoping to capitalize on dissatisfaction with deep tax cuts passed by former Republican Governor Sam Brownback that led to a state fiscal crisis. Colyer was appointed to the seat after Brownback left office to serve in the Trump administration.
Kobach has led a crusade to end what he describes as rampant voter fraud, even though very few cases have been prosecuted in the United States. He served as the co-chairman for a panel convened by Trump to investigate voter fraud, which was later disbanded after most states declined to share information with the panel.
Three other states held nominating contests on Tuesday, including a battle for governor in Michigan in which mainstream Democratic candidate Gretchen Whitmer beat progressive Abdul El-Sayed. Whitmer received more than half of the vote as Democrats angle to take back the governor's office in that Midwestern state.
