JEFFERSON CITY, Mo. – Written off by many in his own party a mere month ago, Republican Rep. Todd Akin has been slowly rebuilding his Senate campaign after apologizing for inflammatory remarks about pregnancy and rape.

Now Akin is approaching a critical week that could determine whether his re-emerging campaign can gain enough momentum to put Missouri back in the battleground column as Republicans attempt to win control of the Senate from Democrats.

Tuesday is the deadline for Akin to get a court order to drop his challenge of Democratic Sen. Claire McCaskill. But Akin says he won't do so. Instead, Akin plans to ramp up his campaign. He's holding a fundraiser Monday with former Republican presidential candidate Newt Gingrich. He's addressing a potentially influential group of pastors Tuesday morning. Then as the drop-out clock ticks down, he's kicking off a statewide bus tour for his Senate bid that will include venerable conservative activist Phyllis Schlafly.
