Andrew Yang, ending his campaign after noting that he faces a shellacking in the New Hampshire Polls, is now one of the biggest ex-candidates whose endorsement of another candidate could actually carry meaning to it https://www.yahoo.com/news/yang-created-buzz-freedom-dividend-010829068.html
Prior to this point, the biggest candidate to drop out of the race was Kamala Harris, who had to pull out of the race due to financing issues and has yet to make an endorsement of her own. Yang, who peaked at 4.9 percent in national polls, never got to the level Harris did, who at one point topped 15% before sliding down to about 4.0% before dropping out..... Yang though managed to make it to Iowa at least, that deserves credit. Candidates who drop out before votes even start getting counted have nearly no weight to their endorsements later on, at least compared to those who stay in.... You think any republican gave a shit about who Rick Perry or whats-his-name from Wisconsin (Scott Walker!) endorsed in 2016? Hell no. Only candidates who actually make it SOMEWHERE into the actual vote have weight to their endorsements.
Yang, by dropping out after Iowa, has only 6 candidates ahead of him in the race: Klobuchar, and the 5 main candidates (Bllomberg, Buttigieg, Biden, Warren, and Sanders). Since the 5 of them will likely stay in the race for a while (Biden, Buttigieg and Sanders have good support, Bloomberg is a fuckin Billionaire) that leaves Yang and Klobuchar as the ones who could really help break the tie among the front runners.
Yang could go in any direction.... He might go business and endorse Bloomberg, he might support Sanders in terms of economics.... Maybe he sticks centrist and goes Biden, or makes a daring bet and go with Buttigieg.... Yangs endorsement might not move the needle much in any one direction, but unlike most people in the race at some point, his endorsement matters, and its up for grabs now that hes out of the race.
