Republican Donald Trump's poll numbers have been rising since the shooting attack on an Orlando gay nightclub that left 49 people dead, according to Reuters' daily tracking poll. Trump, the presumptive GOP presidential nominee, had been on a downward trend against Democrat Hillary Clinton over the last week, and an NBC News/SurveyMonkey poll released Tuesday reflected that with Clinton boasting a seven-point lead.Trump's numbers in the NBC poll reflect the struggles he had last week after he slammed the judge presiding over the Trump University civil lawsuit, saying he can't be fair because of his Mexican heritage, Mediaite notes. But the NBC poll was taken before Sunday's shooting. The Reuter's daily tracking poll shows Trump rebounding after he began vowing to fight radical Islamic terrorists and attacking what he called the Obama administration's weak efforts on the issue.Trump also doubled down on his call to ban all Muslim immigration until radical Islamic terrorism is under control.That poll showed Clinton leading Trump by almost 13 points on Sunday, but has been cut to 8.5 points on Tuesday.Clinton's numbers dropped from 40 percent Sunday to 39.1 percent Tuesday, while Trump's rose from 28.4 percent to 30.9 percent.
