Republican Sen. Dean Heller leads Democrat challenger Jacky Rosen by 47 to 45 percent in a NYT Upshot/Siena College poll released Thursday.
The poll offered various results weighted “by age, party registration, gender, likelihood of voting, race and region, mainly using data from voting records files compiled by L2, a nonpartisan voter file vendor.”
When weighted by “census data instead of voting records,” Heller still came out ahead of Rosen by two points.
When not weighting for party registration, Heller came out three points ahead.
Nearly equal percentages of respondents wanted to see Democrats in control of the U.S. Senate or wanted to see Republicans in control, 48-47, respectively.
