A newly released poll funded by Planned Parenthood found that nearly half of likely voters would be less likely to support Sens. Dean Heller (R-Nev.) and Jeff Flake (R-Ariz.) in 2018 if they voted to defund the women's health organization.
Heller and Flake are considered the leading targets for Democrats aiming to win some Senate seats ahead of a difficult 2018 Senate map.
In Nevada, the poll shows Heller in a close match-up with a generic Democratic opponent, leading 41 to 38 percent, within the survey's margin of error.
