1) Will Joaquin Castro get in the race.... and who would win O'Rourke or Castro?
2) And do either have a chance of upsetting Cruz?
3) Also... why is Julian Castro not thinking about running? Is he looking at Governor or potentially the Presidential Primary?
1. Castro would win a primary.
2. If Trump's approvals are below, say, 40%, and his disapprovals are over 60%, Joaquin could beat Cruz if he ran as a moderate.
3. Julian Castro seems to have no legislative ambitions. IIRC he didn't like his time on the City Council.
