This is a link to the senate members, but you can also check out house of rep. too.
This link has their voting record and compares them to their party and the opposition part stance. It also has tools like best attendance, worst attendance, % with party, % against party....
Be aware that for the guys running for the last year or so, they have missed a lot of votes due to campaigning.
I would recommend reading through some of the bills that they vote on. It may help explain some of the (Changes in position). The votes are often lots of things lumped together sometimes related, sometimes not. Often they have to choose to vote for a couple things they want (like more funding for FIRST) vs. things they don't want in the same bill (Underwater bridges from LA to Hawaii). I hope hawaii has a good since of humor

Consider it the Congress Scouting System. Who did what they said they would and who didn't.
Since 3 of the 4 persons on the 2 main tickets are senators, you can actually get some data on what they really voted for (or against).
