Republicans enjoy a 50 percent to 43 percent advantage over Democrats among registered voters, the highest yet in Gallup’s weekly tracking of the 2010 midterm elections. But a Republican victory in November will mean nothing if it means more GOP business as usual. That is why it is critically important for congressional Republicans to put forward a concrete agenda before the election as an alternative to that of big-spending congressional Democrats. Instead, Republicans appear satisfied to fall back on a one-plank platform: “We’re not the Democrats.” That won’t cut it because, as pollster Scott Rasmussen recently told the Wall Street Journal, the GOP will benefit from voters’ desire to oust the party in power, but “75 percent of Republicans say their representatives in Congress are out of touch with the party base. Should they win big this November, they will have to move quickly to prove they’ve learned lessons from the Bush years.”
