Even as Greg Abbott and many fellow Republicans were still basking in what they called Texas' "most conservative 48 hours" in history, a former one-term state senator announced he would challenge the governor from the right in next year's GOP primary. Don Huffines, a scion of a Dallas family that made its fortune in the auto dealership business and a co-founder of a prosperous real estate development company, announced his candidacy in a series of tweets and retweets Monday. He promised "to finish the wall," eliminate property taxes and protect "election integrity." In one of the tweets, Huffines signed with the line: "An Actual Republican."
