There are 2 movements against Mel Martinez after his support of illegal immigrants getting amnesty. The fisrt group is Republicans against Martinez who are looking at him not even making the primaries.

The second group has a petition to recall Senator Martinez. It is open to all Americans and not only those in Florida.

This could prove to be a very costly error for him. I don't think he has realized that he has shot himself in the foot as he is still talking about reintroducing the immigration bill.
