Obama bested John McCain 365-173 and Bill Clinton's two victories were in the same range. George W. Bush's two electoral college victories were narrow; he won just 271 votes in the disputed election of 2000 and 286 in his 2004 reelection.
So 0bama's electoral margin was 192 - and former-President Bush's margins were 271 and 286 ... say, exactly who had a greater margin of victory?
Obama did electorally
Bush only had a 6 electoral vote victory in 2000, and I think 26 in 2004?
Meanwhile Obama pretty much doubled up McCain
2000:
Bush 271
Gore 266
2004:
Bush 286
Kerry 251
