In these days of wets, moderates and hardliners, a party rosette is no indication of the finer make-up of a politician. So many voters are unsure what their MP is really like.
Baby-holding and door-stepping is all very well in the heat of an election campaign, but what has he or she done for the rest of the parliamentary term?
"Put me down and tell me how you voted on Lords reform."
Two websites, theyworkforyou.com and publicwhip.org, try and address this.
In the first, you can see how your MP voted and how he or she performed in debates. And in the second, there's a rebellion rating and a chance to match him or her against MPs who vote the same way.

David, we don't consider that a flaw. The MPs are being held to account for all their votes on the Iraq war. Surely that is the right thing to do? We're open about exactly how we do this, you can click on a link to see exactly the list of votes that we've selected to judge them on.

I see that offering the baby a year's supply of rusks to punch John Prescott did the trick!
The infant is clearly making a fist. The caption should read "Hit me baby one more time."
Do not take theyworkforyou's word for it about the policy stances of MPs. Their way of working it out is flawed: they include votes on separate issues in the analysis. For example, an MP is only counted as being against the Iraq war if they also voted for inquiries into the war, even though that vote was held months after.
