WHITFIELD: New Hampshire ground zero today for Democrats running for president as 19 of 20 candidates looking to gain support with speeches today at the state's Democratic Party convention.

CNN Political Reporter Arlette Saenz is in New Hampshire with the very latest. Arlette?</s>ARLETTE SAENZ, CNN POLITICAL REPORTER: Well, Fred, we're here at the New Hampshire Democratic Party's state convention. A big weekend for these 2020 contenders. There are 19 of the 2020 Democrats running for president here bringing their pitch directly to granite state voters in this first in the nation primary states. You've seen many of the campaigns coming out with strong organizing forces here at this event but also kind of tailor their message and take their pitch to voters. For many of the candidates who are here at this convention, they're not going to be making it on the debate stage. So this gives them a chance to try to sell their message, sell their brand of politics to New Hampshire voters who are many of them just starting to tune in after the Labor Day holiday. They're just starting to take a closer look at these candidates as they take a more -- move into a more serious phase of the campaign. So far this morning we've heard from Joe Biden, Cory Booker, Pete Buttigieg, Kamala Harris. In a short while, Bernie Sanders and Elizabeth Warren will be speaking here. Both of those senators from neighboring states, and you've recently in polls seen Joe Biden, Bernie Sanders, and Elizabeth Warren really leading the Democratic primary field. So, all of the voters here at this convention are hearing this pitch from the candidates as they get closer to making their decisions about who they'll nominate come 2020. Fred?</s>WHITFIELD: All right. Quite the raucous, exciting crowd back there. Arlette Saenz, thank you so. Appreciate it. All right, coming up at 2:30 p.m. today, we'll speak with one of these candidates at that New Hampshire convention, Congressman Tim Ryan joining us live right here on CNN.
