AUSTIN — How the mighty fall.
If some pundits are right, Lt. Gov. David Dewhurst — the presiding officer of the Texas Senate — will soon be voted out of the powerful office he has occupied since 2003.
Dewhurst, a multimillionaire widely viewed as an establishment Republican, is the underdog in Tuesday’s GOP primary runoff because in the four-candidate race of March 4 he received 28 percent of the vote, a distant second to state Sen. Dan Patrick of Houston, a tea party favorite.
