Can Republican's prevent Obama from making new appointment? I think appointment should be made by the new President. Obama lame duck, USSC lifetime position, so if new Justice is say 46 years old to 50 years old, he or she can be on bench for 30 years or even 40 years. Obama choose Leftist of course, so your First and Second Amendments might be at risk.
The new President should make this appointment IMHO.
A''lame duck'' president or lame duck congress is the president or congress between the November election and the time of the inauguration of the newly elected President and newly elected congress... so, when a new president is elected in November, until the new President is inaugurated in January, the old President is said to be a "lame Duck" President....
and for congress to be a lame duck congress, it is the period between the November election, when a new Congress is elected and when the new congress members get inaugurated in January.
We are not even close to this "Lame Duck" period.
In fact, Obama has gotten more done this year with Congress than he has in most all of his other years in office with congress...Congress actually passed a budget he approved of and signed just a couple of months ago.... he is not a Lame Duck, until a new President is elected...
and even then, it is NOT ALWAYS a Lame Duck session,
As example, if the new President elected is the president's vice President, and the new Congress elected majority has the same party affiliation as the president and the one that existed before the elections, it is NOT a lame duck session at all...
