Minnesota Republican Michele Bachmann currently has 7-to-4 odds of emerging victorious from the Iowa caucuses, says a British bookmaking site. On both sides of the big pond, however, bookies and the Iowa Electronic Markets are pointing to President Barack Obama to give a repeat performance in the general. Ladbrokes.com , a London-based gambling company in existence since 1886, had Bachmann at 5-to-2 odds just two weeks ago, but now sees the Congresswoman as a safer Iowa bet — although perhaps not as ultimately profitable as some other possible wagers.
