The image above shows the results of the newest Texas Lyceum Poll -- done between January 10th and 19th of a sample of 431 likely Texas Democratic primary voters, with a 4.89 point margin of error.
Texas will send 228 pledged delegates to the national convention. As this stand right now, Biden and Sanders will get the bulk of those delegates, and a few could go to Warren. No one else is close to the required percentage (15% statewide or in the state's senatorial districts).
