Thanks to Chips at >> TheObamaDiary <<for this ! It all began on this day, January 4 2005. Barack Obama was sworn in as a United States senator. He would start his presidential campaign just 2 years later he and in 2008 he would win the Democratic parties nomination for President of the United States and then handily defeated John McCain to become the 44th President of the United States. It’s amazing when you think about it !
