As Barack Obama continues to cruise through the post-Super Tuesday Democratic primaries and caucuses, the Illinois Senator has recently made claims during his stump speeches that he is more electable than Hillary Clinton against presumptive GOP nominee John McCain.

Recent head-to-head state polling from across the nation conducted during the past week does indeed find Obama performing much stronger against McCain than does Clinton.

Obama currently performs better than Clinton in 10 of 12 states with polls ending during the past week: Iowa (net +13), Kansas (+18), Michigan (+8), Minnesota (+20), New Jersey (+1), New York (+10), Ohio (+2), Oregon (+9), Virginia (+5), and Wisconsin (+17).

Clinton performs better than Obama when matched up against McCain in just Florida (net +10) and Pennyslvania (+1) in these 12 states. It is worth noting that these are two states in which Obama did not (Florida, due to DNC rules) or has not yet (Pennsylvania) campaigned.

Overall, these polls indicate McCain would defeat Clinton in 8 states (Florida, Iowa, Kansas, Minnesota, Ohio, Oregon, Virginia, Wisconsin), Clinton would win 2 states (New Jersey and New York), with 2 states deadlocked (Michigan and Pennsylvania).

Obama, however, would defeat McCain in 6 states (Iowa, Michigan, Minnesota, New Jersey, New York, Wisconsin), McCain would win 3 states (Florida, Kansas, Virginia) with 3 states essentially tied (Ohio, Oregon, Pennyslvania).
