HMM: Poll: Cruz within 3 points of Trump nationally.

Republican presidential candidate Donald Trump holds a slim three-point lead over rival Ted Cruz nationally, according to a new poll released Tuesday.

Trump has 30 percent support, according to the NBC News/Wall Street Journal survey, with Cruz at 27 percent.

Last month’s version of the same poll found Cruz two points ahead of Trump. It was the only poll since November to show someone other than Trump leading the field nationally.

Tuesday’s results show a tightening in the GOP field overall, with 10 points separating all GOP candidates.

John Kasich is in third place with 22 percent, with Marco Rubio behind him at 20 percent.

Kasich’s support is double the 11 percent he got in last month’s version of the poll.

Stay tuned.
