UPI/CVoter poll: Clinton continues gaining ground at Trump's expense

Democratic presidential candidate Hillary Clinton and running mate Sen. Tim Kaine take the stage at a rally in Pittsburgh as part of their bus tour following the Democratic Convention on Saturday. The UPI/Cvotr daily tracking poll shows Clinton continues to enjoy post-convention bump. 

WASHINGTON, Aug. 5 (UPI) -- Data for the UPI/CVoter daily presidential tracking poll has now fully incorporated both political conventions one week after the Democratic National Convention ended and it shows Hillary Clinton's post-convention bump has largely erased the one Trump enjoyed after his own gathering a week earlier.

Clinton's standing in the poll has steadily risen over the course of seven days while Trump has backslid to a level of support slightly better than where he was prior to the start of the Republican National Convention.

The poll also fully incorporates a viral moment at the Democratic convention. On the gathering's final night, Khizr and Ghazala Khan, the parents of a Muslim soldier killed fighting in Iraq, appeared. Khizr Khan delivered a forceful denunciation of Trump for his lack of military service and his proposal to ban Muslim immigration.

While the speech itself is now fully incorporated into the UPI/CVoter polling data, the resulting feud between Trump and the Khans, which stretched into this week, may still not have been felt.

The poll has also not fully incorporated other negative headlines this week for Trump, including the backlash from Republican Party leaders for his comments declining to endorse House Speaker Paul Ryan and Sen. John McCain, or the candidate's insistence at two rallies that he had viewed video of Iranians taking in $400 million in cash from the U.S. government, after which he said he had actually seen U.S. prisoners returning from Iran in Switzerland.
