Why is Greg Abbott still raising money for his race for governor when he already has enough stashed away to win two or three races? Abbott is on his way to assembling the largest campaign war chest in Texas history, but it’s not because he’s worried about Wendy Davis.It’s because Abbott knows he is likely to face a future race against the real threat to his political career in 2018: Dan Patrick (we might as well call him “lieutenant governor-elect”). He and Patrick are on a collision course for the Governor’s Mansion that year, when Abbott will be running for reelection and Patrick could mount a serious primary challenge.
