not
because 政见不同, not at all!

but
because
you are naive on this side
&
she is naive on the other side

政见不同 is easy to settle down,
based on A, you believe B,
based on C, she believes D,

for everyday life as a couple,
neither A or C is more important
than the price of eggs,

one example: abortion
Obama believes baby in mother's womb is not a human being,
as such, mother has right to choose KEEPING or ABORTING,
Bush believes baby from the beginning is a human being,
as such, mother has no right to kill a baby of hers own,

clear?

however, Bush and Obama bear no difference on asking
Gate to run the defense department.
