No the before the Utah primary the House leadership was scared to death of Tancredo. When Cannon won they realized that Tancredo is a paper tiger. They are now ready to pass legislation and Pence has the best plan. Pence is now carrying the immigration issue flag.
Having a long-time incumbent representative win a primary 56/44 is not exactly a convincing win, especially when the opponent is a single-issue candidate that seems a bit short of being mentally balanced.
I don't see any pro-enforcement Republican representatives facing serious primary challenges.
