HoweHoweDon’t look for an endorsement from the Mainstream Coalition’s political action arm on Steve Howe’s campaign resume.

The board of MainPAC, an affiliate of the politically moderate Mainstream group, voted to endorse Howe, who is running against Johnson County District Attorney Phill Kline in the Aug. 5 GOP primary.

But the conservative Howe turned down the endorsement.The former assistant district attorney, fired by Kline when he took office, is holding together a fragile coalition of GOP conservatives and moderates.

For social conservatives in Johnson County, the “secularist” Mainstream Coalition is the enemy. Howe doesn’t want to be regarded as sleeping with the enemy.

It could cost him critical conservative support.
