The mud's not sticking to billionaire Donald Trump.
The controversial Republican presidential candidate has maintained his lead, despite more negative publicity - in fact, he's even surged in the latest CNN poll.
The poll was the first since the Republican debate where he made controversial comments about a female moderator, seeming to suggest she was tough on him because she was menstruating.
It showed Trump polling at 24 percent, up from 18 percent, with polls by Fox News and NBC showing similar results.
US correspondent Sandy Hughes talked to Paul Henry this morning about Trump's latest surge in the polls.
