Donald Trump has seen a slight surge in the polls after last week's Republican National Convention.
Trump gained three percentage points in the new "USC Dornsife/LA Times Presidential Election Daybreak Poll," which showed the Republican with 45 percent of the vote to Democratic rival Hillary Clinton's 41 percent. The poll, however, has a margin of error of plus or minus 3 percentage points.
Meanwhile, the latest Morning Consult poll had Trump leading Clinton by 4 percentage points, 44 percent to 40 percent. Morning Consult's polling memo says that's "a sizable swing from the past week, when the former secretary of state was clinging to a 2-point lead."
The Morning Consult survey has a margin of error of plus or minus 2 percentage points.
Trump also gained six points in a new CNN/ORC Poll. He leads Clinton in that survey 48 percent to 45 percent. When Libertarian candidate Gary Johnson and Green Party candidate Jill Stein are included, Trump is still ahead of Clinton in the poll, 44 percent to 39 percent.
The poll's margin of error is plus or minus 3.5 percentage points.
