Donald Trump has now grown his lead over Hillary Clinton in Rasmussen Reports’ first weekly White House Watch survey.

Trump earns 42% support to Clinton’s 37% when Likely U.S. Voters are asked whom they would vote for if the presidential election were held today. But Rasmussen Reports’ latest national telephone survey finds that 13% prefer some other candidate, while seven percent (7%) are undecided.

At the beginning of this month, Trump, the presumptive Republican nominee, posted a statistically insignificant 41% to 39% lead over Clinton who is still expected to win the Democratic presidential nomination. Fifteen percent (15%) favored someone else, and five percent (5%) were undecided. […]

Trump now gets 76% of the Republican vote, while Clinton has 72% Democratic support. Thirteen percent (13%) of Democrats prefer Trump, while nine percent (9%) of GOP voters favor Clinton. Among voters not affiliated with either major party, Trump leads 41% to 28%, but 31% of these voters either like another candidate or are undecided.
