As some superPACS throw millions of dollars into the Republican primaries, others, such as American Crossroads, are quietly preparing for the day after the primaries end. American Crossroads — with $15 million on hand as of Jan. 1 — stands to be one of the central elements of the Republican effort. "SuperPACs are a different incarnation of an old idea, which is that you can't stop people who have strong preferences about expressing their ideas in elections from doing so," says Robin Kolodny, a political scientist at Temple.
