Florida Republican Sen. Marco Rubio’s latest fundraising letter completely ignores his signature issue: his work with Democrats to rewrite the nation’s immigration laws and add 46 million immigrants by 2033.

“Now, with the full weight of the liberal Washington elite’s attack machine firmly fixed on me in a frantic attempt to diminish my effectiveness… I’m reaching out to ask you to lend me a hand today,” says the letter, which is signed “Proud to Stand, Marco Rubio.” …

But Rubio has been hammered by former Alaskan Gov. Sarah Palin.

“It’s beyond disingenuous for anyone to claim that a vote for this bill is a vote for security… This bill isn’t about fixing problems; it’s about amnesty at all costs,” Palin wrote in a Facebook post in late June.

Rubio has been distancing himself from his liberal allies since the Senate approved the bill.
