Maybe...though even while on the same side of this issue...I'm not a fan of Tancredo. To put it mildly. :-)
I'd probably write-in Hayworth or Sessions instead.
I don't really care whose name we use, but our message would stand a better chance of being heard if large numbers used the same name as a write-in in the primaries. There's really no chance (or even hope) that they could actually win.
