RALEIGH, N.C. — North Carolina Republican Sen. Thom Tillis has entered the home stretch of his competitive and costly re-election bid with nearly $2.4 million more cash on hand than Democratic challenger Cal Cunningham, according to campaign finance reports filed with the Federal Elections Commission on Thursday.

But in the period from July 1 to Sept. 30, Cunningham raised far more money than Tillis, raking in more than $28.3 million. Tillis raised less than one-fourth of that, bringing in less than $6.6 million over the same period of time.
