    Trump's supporters are incredibly enthusiastic about the coming election, and largely committed in their support for him. Nearly 8 in 10 say that they are more enthusiastic about voting this year than in previous elections, among Republicans who are not supporting Trump, just 39% say they are more enthusiastic than in years past. Likewise, 78% of Trump's backers say they will definitely support him vs. 22% who say they could still change their minds. Among those backing other candidates, 57% say they are committed to their chosen candidate.
    The survey asked those Republicans not currently backing Trump whether they would support him if he became the party's nominee, and just a quarter of Republicans overall say they probably or definitely wouldn't support him in November. That's about the same as the share saying they wouldn't back Rubio or Cruz.
    Trump is widely viewed as the candidate in the field who would be most effective at solving the country's problems, 51% vs. 17% for Cruz, 13% for Rubio and 10% for Carson, and as being best able to handle the responsibilities of being commander-in-chief, 48% say so, compared with 17% for Cruz and 15% for Rubio. The billionaire is also seen as the one who best understands the problems facing people like you, 46% Trump vs. 18% Cruz and 15% Rubio.
    As accusations of dishonesty have flown between Trump, Cruz and Rubio, voters say they are more apt to see Trump as honest and trustworthy. Asked who of the five candidates is most honest and trustworthy, 35% name Trump, 22% Carson -- who has largely stayed out of the mudslinging - 14% Cruz and 13% Rubio.
    On the Democratic side, Hillary Clinton tops Bernie Sanders 55% to 38% in the new poll, a slightly wider margin than she held in late January before any primaries or caucuses were held.

    There are sharper demographic splits among the Democratic electorate than on the Republican side. Men, younger voters, independents and liberals are all about evenly split between Clinton and Sanders, while Clinton's lead rests on large advantages among women, older voters, Democrats and moderates.
    Democrats are more apt than Republicans to say they would support either of the remaining top candidates should they become the nominee. Just 15% each say they wouldn't back Clinton or Sanders.
    Clinton tops Sanders handily as the candidate who would be more effective at solving the country's problems and can better handle the responsibilities of being commander-in-chief, but Sanders fares better than Clinton on honesty, 59% say he is more honest and trustworthy vs. 36% who say Clinton is. Overall, voters are split on whether Clinton or Sanders better understands the problems facing people like you, 49% say Clinton, 48% Sanders.
    The CNN/ORC Poll was conducted by telephone February 24-27 among a random national sample of 1,001 adults. Results for the 418 registered voters who are Democrats and Democratic-leaning independents have a margin of sampling error of plus or minus 5 percentage points. It is the same for results among the 427 Republican and Republican-leaning voters.
