Houston Sports in 90s what was going on

At the same all 3 major sports teams demand new stadiums or they are moving. We were a top 5 city but close to having no professional teams.

Houston Rockets get new owner and immediately win 2 championships. Les Alexander then demands new arena or will move team to Louisville. Initial vote fails but 2nd vote passes.

Houston Astros around same time want new ballpark or will go to Washington DC. Voters passed their stadium bill on first try.

Houston Oilers demand new stadium and basically told no. It wasn’t even up to vote.

What were the politics like. How did Astros get a vote approved for new stadium while the Rockets at the peak of popularity had to try twice? And who was the bigger dbag…Lanier or Adams?
