Is there any chance that JK Rowling modeled Voldemort on Hitler AT ALL?

I keep coming over the similarities like:

• The fact that Voldemort wanted to take over everything (though i know that this CAN be debated)

• He wanted only pure-bloods, just like Hitler wanted only Aryan's. Then again...in Hitler's eyes...Aryan's were "pure-blood"

and probably more...that i cant think of at the moment

Any chance?
