I think it's a combination of both. He's young and idealistic but he's able to speak to a lot of issues and not sound distant or like he hasn't experienced them. I used to live in El Paso (My Dad was stationed in Ft Bliss for five years) and feel like he at least connects with people and understands border and immigration policy far better than some people do. His campaign basically was all through donations from people. No corporations or PACs donated. He visited every county in Texas in a mini-van and sounded like Bernie Sanders did at the end of his election cycle because his voice was gone. He did absolutely no polls so none of that stuff you see in the West Wing where they hire people to do like a small sample of how do you feel about this or that for the campaigner. The best thing he did for Texas was energize Democrats to start registering people to vote, get out and talk about things with people and build a kind of foundation that maybe we can carry into making Texas a purple state instead of all red. It was done all through Facebook posts and social media where Beto seems to connect better which is good because old style Reagan voters eat a lot of red meat and will die out soon so we need to start getting younger voters. He's had some hickups - which you can see when he's knocked on doors of some dyed in the wool crazy GOPer who's obviously going to be antagonistic to a Democrat and films the encounter and posts it. But I think he's honest. Or least comes across that way as opposed to Ted Cruz. None of his ads came out from Beto said anything terrible about Cruz which was kind of the nicest part of the campaign. Just positive moving forward type messages.
If Democrats can get Nancy Pelosi and maybe Schumer to go away I think the next election cycle can see more change.
