The CBS Background Tracker Poll gave Hillary Clinton a sliver of a lead over Donald Trump. The source of her minor boost was the Democratic National Convention [DNC]. She matched the Republican presidential candidate’s boost, and moved slightly ahead of him.
The national poll showed Clinton with 43 percent of the total support, compared to Trump’s 41 percent. After the Republican National Convention [RNC], Trump led 42 percent to her 41 percent last week.
Granted, Clinton solidified her Democratic base during the DNC, but the partisan voters remain mostly fixed. The survey interviewed voters across 11 battleground states both before and after the DNC. It did show that Clinton gained with undecided Democrats, but neither Democrats nor Republicans are changing parties.
The Democratic message is not resonating with people. Only 40 percent of any party like the way the Democrats and candidates described the state of things in America today, and 45 percent disliked it. The latter group consists primarily of independent voters who plan to vote for Donald Trump.
Voters left with mixed feelings about the Democratic convention and divided upon party lines. Overall, they felt somewhat more likely to say “hopeful” than “pessimistic” or “scared.
Over one-quarter of the Republicans, 27 percent, said Clinton’s speech and the Democrats scared them. A greater number of voters were scared after Trump’s speech at the DNC, 36 percent.
Democratic voters see a mending of the previously divided party. They strongly liked how the convention spoke about the losing Democratic presidential candidate, Bernie Sanders, and his supporters. However, Sanders’ supporters divisiveness boiled through occasionally on the convention floor.
The majority of the voters said they wanted to hear more about the economy from the Democrats. Fifty-four percent of the voters said they would have liked to have heard more about changing Washington, D.C.
Of independents, 25 percent said they felt more positively about Clinton after the convention, but that didn’t change their vote. Trump didn’t change Democrats’ views about him after the RNC, either. Republicans said their opinions of Clinton stayed the same or became worse.
