Four days ago we wrote that Ted Cruz was saying the right things to warm a conservative's heart. Today The Washington Post's Chris Cillizza judges that Sen. Cruz is running the most letter-perfect campaign of the entire GOP field, bar none.
Cruz stays on message, doesn't get in fights with front-runners (Trump), and raises money faster than he spends it. One other key Cruz characteristic, he is roundly hated by everyone in Washington the GOP base hates.
That makes Ted the enemy of their enemy ... in other words, their friend. The GOP base would rather have its representatives in Washington shut down the government than have them go along with the (mostly Democratic) status quo. Ted Cruz tries to act on this preference, hence the loathing he attracts.
