A new Morning Consult poll published on Tuesday reveals presumptive Democratic nominee Hillary Clinton’s lead over presumptive Republican nominee Donald Trump dropped to only one point within the margin of error.

Forty-one percent of voters surveyed said they prefer Clinton while 40 percent said they prefer Trump. However, Clinton’s one point lead is within the plus or minus two percentage point margin of error.

The previous Morning Consult poll had Clinton leading Trump by five points. This is the best showing the billionaire has had against Clinton in a Morning Consult head-to-head matchup since the primaries ended.

Independents preferred Trump over Clinton by one point, 33 percent to 32 percent.

As for Congressional races, 43 percent of voters said they will likely vote for a Democrat over a Republican.

The poll was conducted with 2,001 registered voters from June 30th through the Fourth of July holiday weekend.
