The meaning of...
I don't understand some parts and words in the following paragraph that talks about Obama Immigration Plan
Mr. Obama's initiative is a real gain, which must be held against the BLOWBACK from Republicans, WHO ARE GRASPING FOR JUSTIFICATION TO MATCH THEIR OUTRAGE and to block him on legal grounds.
PS: the capital letter is the part that I don't understand, the meaning.
Grazie ragazzi!
