CEDAR RAPIDS — With 75 days until Iowa’s first-in-the-nation presidential caucuses, former Vice President Joe Biden is planning an eight-day, 18-county “No Malarkey” bus tour of the state that includes a stop in Cedar Rapids.It’s part of his effort to “work harder than anyone else to earn the support of Iowans,” according to Biden for President campaign manager Greg Schultz.“When Joe Biden first announced he was running, he told Iowans they’d be seeing a lot of him — and he meant it,” Schultz said Wednesday.
