I attribute no such motivation to Martinez. I merely note that, between the lines, he all but admits that there is a problem ... unintentionally, in my opinion. Martinez advocated undermining citizenship requirements before with amnesty, and he’s advocating it again. Just like McCain, just like Obama, just like Lindsay Graham, just like so many others who apparently envision some wonderful, transnational future for themselves. A self-styled citizen of the world invariably hates the Constitution. It’s an obstacle.
Obviously, they are feeling the need to respond to this issue due to the volume of calls and letters. Since multiple people have received these from different critters, it means the message is getting out in large enough numbers that it is necessary to respond. No other reason for RINOs than political expediency.
