ASTROTURF AIN'T CHEAP:

The Tea Party Patriots Citizens Fund, which blew through nearly $2 million on expenses such as fundraising, polling and consultants in the first three months of this year, is not alone in its meager spending on candidates.

A Washington Post analysis found that some of the top national tea party groups engaged in this year's midterm elections have put just a tiny fraction of their money directly into boosting the candidates they've endorsed.

The practice is not unusual in the freewheeling world of big-money political groups, but it runs counter to the ethos of the tea party movement, which sprouted five years ago amid anger on the right over wasteful government spending.
