Generally, Democrats have had a slight lead, so this may be indicative of positive movement for November.
Via Daily Wire:
For the first time in four years, the Republican Party has a higher favorability rating than the Democratic Party, but only by one point. The GOP has also made big gains in favorability among members of its own party.
Gallup reports that 45% of Americans view Republicans favorably, up from 36% last September. For Democrats, 44% see them favorably, unchanged since last year.
“Only one other time in the last decade has the Republican Party had a significantly higher score than the Democratic Party,” Gallup reported. “That one exception came in November 2014, immediately after elections that saw Republicans capture control of the Senate and expand their majority in the House, when 42% rated the GOP favorably and 36% the Democrats.”
