Two more NBC News/Marist polls paint a mixed picture for Democrats in the race for the Senate, with a tie in one state, and a strong Democratic lead in another over a one-time Republican star.
In Iowa, where longtime Democratic Sen. Tom Harkin is retiring, Democratic Rep. Bruce Braley and Republican state Sen. Joni Ernst are tied at 43 percent each. The poll was conducted from July 7-13, and has a margin of error of plus or minus 2.5 percentage points.
Meanwhile in New Hampshire, Democratic Sen. Jeanne Shaheen leads former Sen. Scott Brown — who moved to New Hampshire and has launched a comeback bid, after he lost re-election in Massachusetts in 2012 — by a solid margin of 50 percent to 42 percent. The poll was also conducted from July 7-13, and has a margin of error of plus or minus 2.7 percentage points.
The polls show that in Iowa, Braley leads among women by a margin of 45 percent to 37 percent, while Ernst leads among men by a similar 48 percent to 40 percent. In New Hampshire, though, Shaheen leads among women by a huge 59 percent to 34 percent, more than balancing out Brown's lead among men of 51 percent to 42 percent. From NBC's analysis: "In this current environment, successful Democratic campaigns are going to need to win female voters by double digits; single digits probably won't cut it."
