It's not the politicians, it's the time and Americas need of foreign and cheap workforce. US's booming economy demanded more workers and Reagan got the bill benefiting millions of immigrants. Look how close Bush was in getting bill passed to legalize illegal immigrants during economic bubble burst. I would rather favor Republicans towards immigrations [Republicans tend to be straight forward and more american then dems]. McCain is the man for immigrants. Democrats tend to be more liberal, hence getting favor from most of the legal immirants, which I consider to be educated and well established. One more things, Bush adminitration got the bill approved for int'l student about OPT. Clinton didn't do that, he went for short term benefit and solution

However, considering various factors I hate to say how McCain can get into White House against Obama. Obama is a smooth talker and a hardcore debater with powerful campign and a very smart dude. As much as I like to see McCain taking over White House, this dream is fading away day after day, week after week. Hope Obama brings good changes for all and not just for lower middle class or what not.
