I'm not so sure it is intended to destroy conservatism as Rush says because to date all it has done is fire up conservatives as no issue has since 9/11.
I would agree that as a means of adding to the literally dying Democrat Party base there is no question of that. Americans know liberalism is a failure as seen by election results since 1968. So if you are the Democrats who are stuck at around 40% of the vote they can count on you go out and bring in new voters.
In this case illegal aliens who can only work at the "jobs Americans won't do" for a short period of time because of the physical demands of the jobs and denied the opportunity to assimilate as others have in the past they are left as dependents of the failed liberal welfare state. God help them.
SO, conservatism is alive. Who are the conservative candidates...who can win elections and "lead" into the future?
Certainly not "Welcome Wagon" Bush!
