This was interesting enough to me to just copy it in full. Check out TigerHawk too.

In the middle of Evan Thomas' insidery campaign book, A Long Time Coming, there is a section on early conflict between John McCain and Barack Obama in the Senate, even before Obama was openly running for president. I thought this bit was interesting for more than one reason:

Obama further aliented McCain on the immigration issue. McCain took great political risks on immigration, defying the GOP faithful who wanted to build a wall across the Mexican border and arrest and detain illegal immigrants. Working with Ted Kennedy and a bipartisan group, McCain came up with compromise legislation to create a guest-worker program. Obama asked to join the group. The senators agreed to hang together to vote against amendments from both the right and the left. Some very conservative senators honored the agreement, voting against conservative amendments -- but Obama did not, voting in favor of a number of liberal amendments. After one meeting, Kennedy chewed Obama out for his fickleness. (Months later, asked by a colleague why he had endorsed Obama for president, Kennedy gave a one-word answer: "Caroline.")

Without reading too much into this anecdote, on immigration, at least, Barack Obama took care of his base and John McCain did not, and his base included Caroline Kennedy. She must indeed be a little bitter about now.
