Donald Trump and Hillary Clinton are effectively tied after the Republican National Convention and the selection of Virginia Sen. Tim Kaine as the Democratic vice presidential candidate, according to the results of a new CBS News national poll out Monday.

Among all registered voters, Trump holds a 44 percent to 43 percent advantage over Clinton, including voters who lean toward a particular candidate. In a three-way matchup with Libertarian nominee Gary Johnson, Trump leads 40 percent to 39 percent, with Johnson earning 12 percent. Those results come on the same day as a CNN/ORC poll that showed Trump with a three-point edge over Clinton in a head-to-head matchup.


The Republican National Convention improved views of Trump, with 50 percent of voters who watched the proceedings saying their opinion of Trump improved, but majorities still said he does not have the proper temperament to be president and is not prepared.

Nearly all voters surveyed said they had made up their minds about whom they are supporting, including 94 percent of Clinton backers and 90 percent of those supporting Trump.

As far as Clinton picking Kaine as her running mate, 49 percent of Democrats surveyed Saturday and Sunday said they are glad, as are 31 percent of voters overall.

The poll was conducted July 22-24, surveying 1,118 registered voters nationwide with an overall margin of error of plus or minus 4 percentage points.
