The Tea Party is getting back on more solid ground — midterm elections where in 2010 the fledgling, grassroots movement unseated so-called “Washington insiders” and helped Republicans win control of the House.

The loosely-knit coalition of groups has already targeted some of the Republican Party’s most established candidates, accusing them of compromising their conservative principles in negotiating with Democrats.

The Tea Party Express even boasted this winter that promising to mount a primary challenge against Georgia Republican Rep. Saxby Chambliss forced him to retire instead of seeking a third term.
