A new poll found former state Sen. Staci Appel, a Democrat, with a 6-point lead over GOP nominee David Young in a top-target House contest in Iowa.  

Appel leads Young, 40 percent to 34 percent, just outside the poll’s margin of error, with 24 percent of voters undecided, according to the independent survey conducted by Loras College  and released on Wednesday. This is the first public survey of the general election in Iowa’s 3rd District, which is an open-seat race because Rep. Tom Latham is retiring. The district is rated as a
Tossup
 by Rothenberg Political Report/Roll Call. The poll surveyed 1,200 likely voters via live telephone calls from Sept. 2 to Sept. 5, and has a margin of error of 5.6 percent.  

President Barack Obama carried the 3rd District by a 4-point margin in 2012, making it a top Democratic target this fall.
