Our take: Elizabeth Warren, Senate candidate, will be speaking at the Democratic National Convention and preparing for her fall campaign by trying to appeal to "both worlds," but she is still creating ripples.

Warren already has a high profile on the national stage, loved (and showered with money) by many liberals even as she is ridiculed on the right. The recent "you didn't build that" controversy is the latest evidence of those firmly set views.

"You built a factory out there? Good for you," she said last year. "But I want to be clear: You moved your goods to market on the roads the rest of us paid for; you hired workers the rest of us paid to educate; you were safe in your factory because of police forces and fire forces that the rest of us paid for. You didn't have to worry that marauding bands would come and seize everything at your factory, and hire someone to protect against this, because of the work the rest of us did."
