Washington CNN  — 

A new poll has Donald Trump riding high in New Hampshire – with more than double the support of former Florida Gov. Jeb Bush – while stripping away supporters from Wisconsin Gov. Scott Walker, New Jersey Gov. Chris Christie and Texas Sen. Ted Cruz.

Almost one quarter of likely Republican primary voters, 24%, said they would pick Trump. That’s double the 12% who picked Bush and well above Walker, Christie, Cruz and others who all came in with single-digit support.

“The controversy over comments about John McCain’s war service do not appear to have slowed the Trump steamroller,” Patrick Murray, director of the independent Monmouth University Polling Institute, said in a statement.

The poll of 457 likely voters was taken between July 23 and July 26 and carries a 4.5 percent margin of error.

Trump performed well among tea partiers, conservatives and younger voters, according to the poll. The bad news in the Trump run comes for Walker, Christie and Cruz, who most Trump supporters said would be their second pick if the reality TV star was not running.

A national CNN/ORC poll of 1,017 likely Republican voters, conducted July 22-25, found Trump leading the pack with 18% support, followed by Bush at 14% and Walker at 12%.
