a quick Google says he lost a race in Nevada a few months ago, then promptly moved to Texas to run in this special election? Lol.
yeah, i don't think he's likely to make the runoff. he's a carpetbagger and arlington doesn't strike me as likely to love this messaging (though maybe most of the population in the district is south of there, dunno really).
the dead rep's spouse is running and will probably get most republican votes.
