The Democratic lead over Republicans in a generic congressional election has largely faded since the beginning of the year, according to a Washington Post-ABC News poll released Monday.

The April 8-11 survey found 47 percent of registered voters would pick the liberal over the conservative if the 2018 midterm elections were held now, compared to the 43 percent who picked the GOP candidate. That difference is at the poll's margin of error.

The Democrats had a 12-point lead over Republicans in January, when they led 51-39.

Currently, House Republicans hold 237 seats compared to Democrats' 193 seats.

The survey was conducted among 1,002 U.S. registered voters and had a margin of error of 4 percentage points.
