They're crying crocodile tears for Aaron, I'm sure. :P
You say that as if politicians haven't taken positions in the past just to win elections (with no intention of following through, or without changing their beliefs on the larger issues raised).
And I'm sure the tears of Democrats are genuine :p
Politicians certainly fail to follow through on their promises. But by publicly supporting an issue they give opponents a way to attack them if they don't follow through. So there is some worth to making a public commitment, especially if it is frequent and loud.
The republicans would have all hackers in jail and on sex-crime registries because you know...they are tough on crime. Not saying democrats are better, but I give republicans no cred on these issues based on their history alone.
