I think they’re motivated by money and power. The new amnesty is neither pragmatic or expedient....well, except to be in a big hurry to make every invader legal.
When you really study the Lobbyists writing these laws and their various ‘non profits’ it really looks more like money laundering than ‘legislation’.

That may be the case for those in power, (McCain, Grahm, etc.) but for the run of the mill supporters such as Allahpundit, Ace of Spades, and kooks like Jeff Winston, it's likely just about votes, and the potential to lose them.
