A new Quinnipiac University national poll released on Monday showed for the first time that one 2020 Democratic Party presidential candidate has a clear lead over the other candidates following in the aftermath of the recently held first-in-the-nation Iowa caucuses.
In the poll, Sen. Bernie Sanders (I-VT) overtook former Vice President Joe Biden as the national front runner with 25% of the vote among Democratic voters and independent voters who lean Democratic.
