I wouldn't say he "wanted to have it both ways" exactly, but I understand what you mean. What he wanted was to win re-election, and although I condemn his tactics once the general campaign was under way, his method of ensuring that he kept himself on the November ballot was sensible and intelligent. He and I probably share the same view that party primaries are merely a way for the respective bases to make themselves feel important, but don't actually need to matter once the general election rolls around.
I still find it amusing that the Democratic party rank-and-file are so hateful towards him when they owe him so much at the moment.
It's not just that; it's basically that he appears to have lied about absolutely everything during his election campaign. He said he wanted to elect a Democrat as president in 2008. Nope. He shifted his rhetoric on the Iraq War closer to the Democrats. Nope. The people in Connecticut are, if I recall correctly, pretty strongly of the opinion that they would not re-elect him again if given the option in the present day.
Have whatever opinions you want, but for God's sake, at least be honest about what the people are going to get if you're elected. It's his fundamental dishonesty that he has shown that I object to, not his opinions themselves.
