Why is that because Obama won by a large margin is everyone saying blacks voted for him cause he is black?

To me it seems like more than just blacks voted for him, and I think a lot of people see him as someone that could lead this country. I wonder why we all cant just stand together with hopes of uniting our country. The funny thing about all of the naysayers a lot of them call themselves Christians but bash Obama so much and so harshly how can you honestly call yourselves God Fearing People? I have been republican all my life and so has my family but honestly after seeing what Palin did to excite all the "racist republicans" scared me so much I could not see her being so close to being president.
