Honestly, she is not. She was not elected by the majority of electoral votes in an election that took place across the entire union. She does hold some real power, however, but she needs to keep in mind that she represents the people of her district and act in their best interests. I think she is fantasizing about impeaching/convicting Pence and then impeaching/convicting Trump.
Spot-on. Members of Congress need to realize that they are not leaders. They are representatives. Big difference.
