POLL: Donald Trump Climbs 6 Percentage Points in One Week After GOP Convention A new national poll shows Trump on the rise after the RNC.

 -- Republican presidential nominee Donald Trump has climbed six percentage points after his party's convention last week, garnering his highest support against Hillary Clinton since last September.

Trump earns 48 percent support vs. 45 percent support for Clinton in a head-to-head matchup, within a new CNN poll's margin of error. Another poll from CBS News out this morning showed the two candidates tied at 42 percent.

Still, the CNN poll shows Clinton's lead evaporating. Just one week ago, Clinton led by a 49-42 percent margin.

One in four Sanders voters still aren't voting for Clinton. Half of those defecting say they plan to vote for Trump and half say they plan to vote for neither. About the same number of non-Trump GOP primary supporters say they aren't backing Trump.

The poll, taken entirely after the GOP convention, was taken July 22-24 and has a margin of error of +/- 3.5 percentage points.

Trump's boost comes as he asserts a commanding lead among white voters without a college degree, climbing to 62 percent -- up 11 points from last week.

Meanwhile, more than two in three voters say they don't think Clinton is honest and trustworthy, a new high in CNN/ORC polling.

But Trump's personal attributes have improved slightly. The number of Americans who say they would be proud to have him be president is up seven points to 39 percent and now 46 percent of Americans say he's in touch with their problems in daily life.
