A new poll out Tuesday indicates Americans are divided about which party they’ll support in this fall’s midterm election, while roughly one in six hasn’t yet made up their minds.

The Politico/Morning Consult poll of registered voters found that if the midterms were held today, 43% would back a Democratic candidate for Congress while 42% would support the Republican candidate.

Another 16% answered “don’t know” or had no opinion.

Republicans have an advantage over Democrats among men (45% to 39%) and white voters (50% to 38%), according to the survey.

But Democrats have the edge among women (46% to 38%), black voters (61% to 12%) and Hispanic voters (42% to 32%) — although 27% of blacks are undecided, as are 26% of Hispanics. 

Looking at the issues, Republicans are favored by voters who say their top priority is the economy (50% to 36%) and security (69% to 23%).

Democrats lead on women’s issues (69% to 10%), health care (64% to 19%), energy (62% to 22%) and Medicare/Social Security (55% to 32%).

On education, Democrats have an eight percentage-point lead (30% to 22%), but a whopping 48% expressed no opinion on the issue.

Midterm elections are traditionally difficult for the political party that controls the White House, and Democrats are widely expected to lose control of both the House and the 50-50 Senate, which would effectively make President Biden a lame duck with two years left in his term. 

While the president’s personal poll numbers appear to be locked in a never-ending downward spiral, the Politico survey indicates that those who hold a “somewhat unfavorable” view of Biden are more likely to vote for a Democratic congressional candidate than a Republican one (38% to 34%, with 28% undecided).

The poll surveyed 2,005 registered voters between April 15 and 17 and has a margin of error of plus or minus 2 percentage points.
