The GOP can win comfortably in 2012 once the 3-5 pts worth of white women who switched to Obama after the collapse in a state of panic and frustration at Bush and the GOP realize their mistake and switch back.
Not if the dems succeed in legalizing 20-30 million illegal immigrants. They will have successfully neutralized the repub gains among independents if they throw in a huge new voting block.
Only citizens are legally entitled to vote, not legal immigrants. The problem that need to be fixed is illegal voting.
