Democrat presidential candidate Hillary Clinton and Republican candidate Donald Trump appear to be competing head to head in the 2016 US presidential race, and as a result, both are scoring high in the polls.

Clinton is now slightly leading the Democrats, while ex-governor of Florida Jeb Bush and Donald Trump are two of the Republican candidates scoring high, a new national poll from CNN/ORC finds.

According to political writer, Ron Kampeas, in a report from the Irish Examiner, Republicans seem to like Trump because of his attacks targeted at each of Clinton's turns, adding that each time the former first lady retaliates, she ends up boosting her standing.

The Wednesday CNN poll showed Clinton ahead of other challengers from the Democratic side by more than 40 percentage points. She stands ahead of vice president Biden, Bernie Sanders, Jim Webb and Martin O' Malley.

For the Republican candidates, Bush is seen to have 19% of the votes and Trump has 12%, Mike Huckabee 8%, and Ben Carson and Rand Paul 7% each.

The CNN/ORC Poll was done via telephone on June 26 to 28, CNN reports. The poll was conducted on 1,017 randomly selected adults, with a margin of error of plus or minus 3 percentage points.

Meanwhile, it appears that Clinton's support extends all the way to Canada, based on a new poll that surveyed how Canadians feel about U.S. politics.

According to the report, if Canadians had to vote for the next president of the U.S., Clinton would surely "win by the largest landslide in the country's history."

The Canadian poll also revealed that the country's voters would willingly elect another Clinton for president and it won't matter who her contenders were. If Clinton were to run against Bush or the real estate mogul Trump, Canadians would still vote the former first lady any time.
