The first night of the second debate for the Democratic Party nomination for president was dominated by progressive Sen. Elizabeth Warren.

Because there are so many Democrats running for the nomination to run against President Donald J. Trump, there have to be two nights of debates. CNN is staffing and broadcasting the debates.

Tuesday night's winner was Senator Elizabeth Warren.

She shared the stage with Sen. Bernie Sanders, self-help author Marianne Williamson, Mayor Pete Buttigieg, Sen. Amy Klobuchar, former Congressman Beto O'Rourke and some others.

Senator Warren showed her knowledge on the issues and presented solutions on the problems that the Democratic Party is focused on today.

Her best line of the night was focused on a more moderate opponent on stage tonight. She sliced her opponent when she pointed out that a solution based message is needed with the statement "why run for president to tell people what we can't accomplish."

Another great galvanizing line from the Massachusetts Senator was about her electability. She rightly pointed out that she remembered "when people said Barack Obama couldn't win and when they said Donald Trump couldn't win."

Warren's attack on the paperwork required by private insurance companies certainly hit home with all Americans. Regardless of a person's opinion on private insurance, nobody likes paperwork or the insurance company bureaucracy.

Senator Warren was the big winner of the first night of the second debate for the Democratic nomination for president.
