democrat vs republican

i have been a registered democrat all my adult life and yes, i voted for obama and yes, i am extremely disappointed in his presidency.  so much so that i have considered changing parties for several weeks now.  my husband is a republican and believe me, there are heated (mildly put) discussions pretty much daily in our house.   I have been doing my due diligence on the current candidates for the upcoming elections, and i was still on the fence until this morning.  a republican i know just made me realize how selfish most republicans are and why i am a democrat.  i appreciate that you work for your money and you dont want to give it away, i get that, but when you know someone who has a need and they ask you to help them out and you tell them you cant afford to help and turn around and blow your ‘hard earned money’ on ridiculous, unneeded and unnecessary items, well that just shows me that i am right in staying a democrat.  i am amazed how some people sleep at night.
