Sen. Elizabeth Warren (D-MA), the epitome of the liberalism represented by the Democratic Party, will run for President of the United States in 2020.

A resolute foe of president Donald Trump, Sen. Warren becomes the first Democrat to declare her intention to run for President against whoever it is the Republican Party chooses as its standard bearer. It remains uncertain if Trump will win the Republican Party nomination for president given his massive and enduring unpopularity at home.

Sen. Warren, 69, is a staunch foe of bloated defense spending and economic inequality. On Monday, she took the first major step toward launching her campaign for the presidency, which has long been anticipated.

She said that no matter what our differences, most of us want the same thing. These things are to be able to work hard, play by the same set of rules and take care of the people we love.

"That's what I'm fighting for and that's why today I'm launching an exploratory committee for president."

She's also famous, or infamous, for her criticism of big banks and corporations.

"America's middle class is under attack," she said. "How did we get here? Billionaires and big corporations decided they wanted more of the pie and they enlisted politicians to cut them a fatter slice."

Despite being a supporter of a strong military, Warren has repeatedly blasted the Pentagon's excessive defense budget. She said it's time to end "the stranglehold of ... the so-called Big Five defense contractors," which are the chief causes of bloated defense budgets that take away money from needed social services.

"The defense industry will inevitably have a seat at the table, but they shouldn't get to own the table," said Sen. Warren.

She said it's time to identify which programs actually benefit U.S. security in the 21st century, and which programs make defense contractors rich -- then pull out a sharp knife and make some cuts.

She is also an unyielding foe of nuclear weapons. Warren has repeatedly urged the Pentagon not to modernize its existing nuclear arsenal. She also wants the U.S. to officially declare a "No-First-Use" policy for nuclear weapons.

She announced her candidacy weeks after she made a foreign policy championing a smaller defense budget; withdrawal of U.S. troops from Afghanistan and the No-First-Use nuclear weapons policy.

She said the U.S. needs to refocus its international economic policies so they benefit all Americans, not just wealthy elites.

Sen. Warren will have to contend with at least two dozen Democrats that have indicated their intention to run for President in 2020.

Trump is looking increasingly vulnerable and isn't assured of the nomination. The increasingly isolated Trump on Jan. 4 will also have to contend with a House of Representatives dominated by Democrats who have vowed to exert more oversight on him. Some Democrats also want Trump impeached at the earliest possible time.
