Donald Trump has soared to a campaign-high 41 percent support among Republican voters in the latest CNN/ORC poll, more than doubling the level of support of nearest challenger Ted Cruz at 19 percent.

According to CNN, not only 4-in-10 GOP voters nationwide are now saying they back the Republican front-runner but also two-thirds of all party voters also agree that he is the candidate most likely to emerge as the formal nominee.

Other than Cruz, no other Republican candidate hits double digit support, with Florida Sen. Marco Rubio standing at 8 percent, retired neurosurgeon Ben Carson at 6 percent and former Florida Gov. Jeb Bush at 5 percent.

Trump's sizable lead is based on his front-runner standing with a number of subgroups, including both men and women, younger and older voters, white evangelicals, conservatives and both self-identified Republicans and independents that lean toward the party.

Support for Trump also appears firm with 70 percent of his backers indicating they've definitely made up their mind to support him, compared to 40 percent for other candidates.

Among GOP voters, Trump also rates as the candidate viewed as best equipped to handle both the economy and illegal immigration, holding 60 to 12 and 55-16 leads over Cruz on those respective issues.

Over the course of the campaign season, Trump has also steadily gained ground on the values issues that are often meaningful among Republican primary voters. In all, 28 percent of GOP voters now believe he would do the best job on social issues, almost double the 15 percent he rated at just four months ago.

The poll also finds Trump is seen as four times more likely to win in the general election (63 to 16 percent) than Cruz, while Rubio nets a 10 percent rating.
