Barack Obama has already held more re-election fundraising events than every elected president since Richard Nixon combined, according to figures to be published in a new book.

Obama is also the only president in the past 35 years to visit every electoral battleground state in his first year of office.

The figures, contained a in a new book called The Rise of the President’s Permanent Campaign by Brendan J. Doherty, due to be published by University Press of Kansas in July, give statistical backing to the notion that Obama is more preoccupied with being re-elected than any other commander-in-chief of modern times.
